Available in PDF, EPUB and Kindle. Book excerpt: In response to RN-AFAPL-08-72-8, a program was initiated to determine the compatibility of Inconel canisters with specific thermal energy storage materials. A uniform temperature vacuum oven and and a 100-min (65 min on and 35 min off) oven control were designed and constructed. The timer-oven system generates the thermal cycle of an energy storage canister in near-earth orbit. An X-750 alloy canister was fabricated, precipitation-hardened, loaded with 215 gm of pure aluminum, and sealed off under high vacuum. It was then fitted with six thermocouples and placed in the oven for a 5000-hr test. Initial temperature measurements indicated that the aluminum alternately melted and froze during each temperature cycle. After 48 hr, only partial melting occurred. After 9 days of continuous cycling, all melting had ceased and the test was terminated. It was found that the canister had ruptured and that its contents were extremely hard. Electron microprobe analysis revealed the contents to be an aluminum-nickel-chromium-iron alloy with a density of 3.2 gm/cc (vs 2.7 gm/cc for pure aluminum). It is evident that the canister material was dissolved by the molten aluminum and that the coefficient of thermal expansion of the resulting alloy was large enough to cause the canister to rupture explosively. Preparations are under way for similar tests using eutectic mixtures of alkali fluorides. (Author).

Download or read book Solar Thermal Energy Storage written by H.P. Garg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy Storage not only plays an important role in conservinq the energy but also improves the performance and reliability of a wide range of energy systems. Energy storagp. leads to saving of premium fuels and makes the system morA cost effective by reducing the wastage of energy. In most systems there is a mismatch between the energy supply and energy demand. The energy storage can even out this imbalance and thereby help in savings of capital costs. Enerqy storage is all the more important where the enerqy source is intermittent such as Solar Energy. The use of jntermittent energy sources is likely to grow. If more and more solar energy is to be used for domestic and industrial applications then energy storage is very crucial. If no storage is used in solar energy systems then the major part of the energy demand will be met by the back-up or auxiliary energy and therefore the so called annual solar load fract]on will be very low. In case of solar energy, both short term and long term energy storage systems can be used whjch can adjust the phase difference between solar energy supply and energy demand and can match seasonal demands to the solar availability respectively. Thermal energy storage can lead to capital cost savings, fuel savjngs, and fuel substitution in many application areas. Developing an optimum thermal storaqe system is as important an area of research as developinq an alternative source of energy.

Download or read book Heat and cold storage with PCM written by Harald Mehling and published by Springer Science & Business Media. This book was released on 2008-08-15 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The years 2006 and 2007 mark a dramatic change of peoples view regarding c- mate change and energy consumption. The new IPCC report makes clear that - mankind plays a dominant role on climate change due to CO emissions from en- 2 ergy consumption, and that a significant reduction in CO emissions is necessary 2 within decades. At the same time, the supply of fossil energy sources like coal, oil, and natural gas becomes less reliable. In spring 2008, the oil price rose beyond 100 $/barrel for the first time in history. It is commonly accepted today that we have to reduce the use of fossil fuels to cut down the dependency on the supply countries and to reduce CO emissions. The use of renewable energy sources and 2 increased energy efficiency are the main strategies to achieve this goal. In both strategies, heat and cold storage will play an important role. People use energy in different forms, as heat, as mechanical energy, and as light. With the discovery of fire, humankind was the first time able to supply heat and light when needed. About 2000 years ago, the Romans started to use ceramic tiles to store heat in under floor heating systems. Even when the fire was out, the room stayed warm. Since ancient times, people also know how to cool food with ice as cold storage.

Download or read book Solar Energy Utilization written by Hafit Yüncü and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until very recently, energy supply of the world has been treated as being nearly inexhaustible. Nowadays about 90 percent of the energy used is obtained from non-renewable resources: oil, natural gas, coal and uranium. These resources are being used up at an alarming rate. To meet our demands we are now searching for new sources of energy. One of these new sources of energy is solar energy which will assume increasing importance. It is free but means must be developed to use it economically. Research is actively under way to reduce the storage cost of this low intensity energy and for the design of economical systems. The purpose of this Institute is to provide an international forum for the dissemination of information on solar energy utilization: fundamentals and applications in industry. This meeting is primarily a high level teaching activity. The subject is treated in considerable depth by lecturers eminent in their field. The other participants include scientists, engineers, and senior graduate students who themselves are involved in a similar research and who wish to learn more about current developments, as well as scientists from other areas who are planning to research on solar energy. The lectures are supplemented by informal discussions designed to encourage the free and critical exchange of ideas. A limited number of contributions are also included. This volume contains both basic and applied information contributed during the Institute. The editors appreciate the cooperation of Martinus Nijhoff Publishezsin making the proceedings widely available.

This promising technology has already been successfully implemented in many construction projects. The aim of this book is to assist the scientists and to provide the reader with a comprehensive overview of the properties that characterize the phase change materials from theoretical and experimental perspectives with a focus on their technological applications. The present status and future perspectives of phase change material are discussed.
