Download or read book Energy Aspects of Acoustic Cavitation and Sonochemistry written by Oualid Hamdaoui and published by Elsevier. This book was released on 2022-08-06 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy Aspects of Acoustic Cavitation and Sonochemistry: Fundamentals and Engineering covers topics ranging from fundamental modeling to up-scaled experiments. The book relates acoustic cavitation and its intrinsic energy balance to macroscopic physical and chemical events that are analyzed from an energetic perspective. Outcomes are directly projected into practical applications and technological assessments covering energy consumption, thermal dissipation, and energy efficiency of a diverse set of applications in mixed phase synthesis, environmental remediation and materials chemistry. Special interest is dedicated to the sonochemical production of hydrogen and its energetic dimensions. Due to the sensitive energy balance that governs this process, this is seen as a "green process" for the production of future energy carriers. Provides a concise and detailed description of energy conversion and exchange within the single acoustic cavitation bubble and bubble population, accompanying physical and chemical effects Features a comprehensive approach that is supported by experiments and the modeling of energy concentration within the sonochemical reactor, jointly with energy dissipation and damping phenomenon Gives a clear definition of energy efficiency metrics of industrial sono-processes and their application to the main emergent industrial fields harnessing acoustic cavitation and sonochemistry, notably for the production of hydrogen

Download or read book Efficiency of heat and work in a regional energy system written by Tommy Rosén and published by Linköping University Electronic Press. This book was released on 2019-12-11 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the largest flows of energy in Swedish municipalities is the fuel-energy flow through the regional combined heat and power (CHP) plant. The customer products from this flow are mainly electricity to the electricity grid and heat to the building sector. There are many ways to describe and examine this fuel-energy flow, and there are many perspectives. This thesis presents one perspective. It is a top-down, analytical and numerical perspective on the efficiency of heat and work in a regional energy system. The analysis focus on the present situation in Linköping municipality and aims at describing the energy efficiency improvement potential. Three subsystems are considered, the regional production of electricity, the regional production of heat, and the regional public transport by bus. These three systems are physically all heat engines i.e. engines that derive work and/or heat from fuel combustion processes. It is important to notice that the analysis in this thesis does not describe the theoretical improvement potential, that potential is considerably higher than the implementable potential, but of no practical use. Instead the analysis is as far as possible based on real world measured efficiencies and efficiency values of best practice (Best available technology). The analysis shows that hardware investments at the CHP plant can improve the electricity generation efficiency and thereby reduce CO2 emissions. The investments are in high pressure turbines, medium pressure turbines and preheaters. The size of the improvement is hard to quantify because it depends partly on unknown factors in the surrounding electricity market. In the studied system CO2 reduction could be as high as 40 - 60 %. The regionally produced biogas would be used more efficiently if it were used in the local combined cycle gas turbine instead of being used in internal combustion engines in buses. The buses would instead be electrically driven. This use of biogas would create a better integrated fuel-energy flow and reduce heat losses. Another improvement is to reduce the system temperatures in the district heating system. The study shows that the efficiency gains, because of lower system temperatures, would increase electricity production by about 1 – 3%, and that greenhouse gas emissions would be reduced by 4 – 20%. However, these improvements are dependent on demand side investments in the district heating system and are therefore slow to implement. Ett av de största energiflödena i svenska kommuner är bränsle/energi-flödet genom det regionala kraftvärmeverket. De konsumentprodukter som detta energiflöde producerar är främst uppvärmning av bostäder och elkraft. Det finns många sätt att beskriva och utvärdera detta bränsle/energi-flöde och det finns många olika perspektiv. Det här arbetet analyserar energiflödet med en analytisk ”top-down” metod. Analysen utgår ifrån den nuvarande situationen i Linköpings kommun och avser att belysa den förbättringspotential som finns med avseende på systemets verkningsgrad. Tre delsystem har studerats, det regionala systemet för värmeproduktion, det regionala systemet för elproduktion och det regionala kollektivtrafiksystemet för innerstadstrafik med buss. Dessa tre system är fysikaliskt värmemotorer d.v.s. de är system som nyttjar termisk energi från förbränningsprocesser för att utföra ett arbete och/eller generera värme. Det är viktigt att notera att analyserna i detta arbete inte avser att beskriva en teoretisk förbättringspotential. Analyserna avser istället att belysa den praktiska, implementerbara, förbättringspotentialen. Därför har arbetet så långt som möjligt utgått ifrån uppmätta data och numeriska värden på verkningsgrader ifrån redan existerande anläggningar eller tekniska komponenter. Analyserna visar att hårdvaruinvesteringar i det lokala kraftvärmeverket skulle öka elproduktionen och därigenom sänka koldioxidutsläppen. De investeringar som skulle behöva göras är investeringar i högtrycksturbiner, mellantrycksturbiner och förvärmare. De sänkta koldioxidutsläppen är svåra att kvantifiera eftersom de delvis beror på okända faktorer på den omgivande elmarknaden. Reduktionen av koldioxidutsläppen skulle kunna vara så stor som 40 - 60 %. Den lokalt producerade biogasen skulle användas mer effektivt om den användes i den lokala gaskombi-anläggningen istället för att användas som bussbränsle som är det nuvarande användningsområdet för detta bränsle. Bussarna skulle istället kunna ersättas med elbussar. En sådan förändring av biogas-användningen skulle innebära ett bättre integrerat energisystem med lägre värmeförluster. En annan möjlig förbättring av kraftvärmesystemet är att sänka returtemperaturerna i fjärrvärmesystemet. Analyserna visar att elverkningsgraden skulle förbättras 1 – 3 % och att koldioxidutsläppen skulle kunna minska med 4 – 20 %. Dessa förbättringar skulle däremot kräva investeringar på kraftvärmesystemets kundsida och bedöms därför vara långsamma att implementera.

This book was released on 2023-12-31 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: Das Energiekonzept und die Beschlüsse der Bundesregierung zur Energiewende sind wichtige Weichenstellungen für die Gestaltung des zukünftigen Energiesystems. So soll u. a. die Energieeffizienz in dem Maße gesteigert werden, dass bis zum Jahr 2050 nur noch die Hälfte des Primärenergieverbrauchs im Vergleich zum Jahr 2008 benötigt wird. In Deutschland leben rund 75 % der Menschen in Städten. Daher sind Städte und Agglomerationen besondere Lebens-, Wirtschafts- und Kulturräume. Als solche verlangen sie nach einem zukunftsfähigen Energiesystem und müssen in hohem Maße energieeffizient ausgestaltet sein. Besonders relevant für die Steigerung der Energieeffizienz ist der Gebäudesektor: In den Wohn- und Nichtwohngebäuden bundesweit entstehen rund 35 % des Endenergieverbrauchs, etwa drei Viertel davon in Form von Wärme. Die von der Bundesregierung beschlossene Energiewende, also der Umbau der deutschen Energieversorgung auf Basis hoher Effizienz und mit weitgehender Nutzung erneuerbarer Energien, kann deshalb nur gelingen, wenn diese Wende nicht nur im Strom-, sondern auch im Wärmemarkt umgesetzt wird (sogenannte "Wärmewende"). Mit Blick auf das energie- und klimapolitische Ziel eines nahezu klimaneutralen Gebäudebestands bis zum Jahr 2050 sind neben einer gesteigerten Energieeffizienz die erneuerbaren Energien in weit größerem Maße in den Wärmesektor zu integrieren. Städte und Agglomerationen bieten aufgrund der großen Hebelwirkung die Möglichkeit, technologische und gesellschaftliche Innovationen ungleich schneller und wirksamer in die Praxis umzusetzen und damit die energiepolitischen Ziele der Bundesregierung zu erfüllen.

Available in PDF, EPUB and Kindle. Book excerpt: This publication is a result of three meetings, each 5 days long, held at the Goddard Space Flight Center on January 24-28, 1983, June 8-14, 1983, and February 13-17, 1984. The meetings were held in the interim between the full operations of the Solar Maximum Mission (SMM) in 1980, and the renewed operations after its repair in orbit in April 1984. Their general objectives were as follows: o Synthesize flare studies after three years of SMM data analysis. Many analyses of individual flares and individual phenomena, often jointly across many data sources had been published, but a need existed for a broader synthesis and updating of our understanding of solar flares since the Skylab Flare Workshops held several years earlier. o Encourage a broader participation in the SMM data anlysis and combine this more fully with theory and other data sources--data obtained with other spacecraft such as the HINOTORI, P78-1, and ISEE-3 spacecrafts, and with the Very Large Array (VLA) and many other ground-based instruments. Many coordinated data sets, unprecedented in their breadth of coverage and multiplicity of sources, had been obtained within the structure of the Solar Maximum Year (SMY). o Stimulate joint studies, and publication in the general scientific literature. The intended primary benefit was for informal collaborations to be started or broadened at the Workshops with subsequent publications. o Provide a special publication resulting from this Workshop. o Provide a starting point of understanding for planning renewed full observations with the repaired SMM.

This book was released on 2017-11-20 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a chemist who is concerned with the synthesis of new energetic compounds, it is essential to be able to assess physical and thermodynamic properties, as well as the sensitivity, of possible new energetic compounds before synthesis is attempted. Various approaches have been developed to predict important aspects of the physical and thermodynamic properties of energetic materials including (but not limited to): crystal density, heat of formation, melting point, enthalpy of fusion and enthalpy of sublimation of an organic energetic compound. Since an organic energetic material consists of metastable molecules capable of undergoing very rapid and highly exothermic reactions, many methods have been developed to estimate the sensitivity of an energetic compound with respect to detonationcausing external stimuli such as heat, friction, impact, shock and electrostatic discharge. This book introduces these methods and demonstrates those methods which can be easily applied.

Download or read book The Handbook of Constitutional and Energetic Herbal Medicine written by Andrew Stableford and published by Aeon Books. This book was released on 2021-01-28 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique and essential textbook bridging the gap between herbal medicine therapeutics and orthodox medicine. Based upon a constitutional approach to treatment, The Handbook of Constitutional and Energetic Herbal Medicine is a synthesis of the traditional herbal approach integrated with biomedical constructs. While this holistic approach to treatment may seem incompatible with the biomedical approach, this is largely due to the lack of understanding of the medical interpretation of holism. In fact, the spirit, mind, body axis can be understood in terms of psycho-physiological processes and principles. It is a matter of interpretation and adaptation of principle. This book will appeal to those involved in both complementary and mainstream medicine seeking a holistic approach which is rational and interpretable in biomedical terms.
