Book excerpt: Master's Thesis from the year 2018 in the subject Engineering - Mechanical Engineering, grade: 7.38, Savitribai Phule Pune University, formerly University of Pune (D.Y Patil School of Engineering), course: Master of Engineering, language: English, abstract: In this experimental analysis of heat transfer variation and its enhancement of the dropped and circular shapes, staggered pin fin heat sink under constant heat flux condition are presented through a conducted experimental comparison between aluminium, stainless steel and iron materials with circular and dropped shaped pin fins. A pin fin is fabricated from heat sink aluminium (Aluminium-Magnesium-Silicon Alloy), Stainless steel and ferrous material with a diameter of 10 mm. The Base plate is also same material and fins are mounted on a base plate with the help of a thread. Various trials were conducted on each material for choosing the best materials for more heat transfer. Also, to choose which is the best shape of pin fins i.e. circular or dropped for enhancing maximum heat transfer. Also, trials were conducted to find out from forced convection from 2D or 1D which is more capable to transferring heat transfer and therefore to choose the best flow of heat transfer model. The total comparison between circular and dropped shaped pin fins was performed in this experimental analysis. Finally the results were validated by using ANSYS R14.5 simulation tool.

Download or read book Gas Turbine Blade Cooling written by Chaitanya D Ghodke and published by SAE International. This book was released on 2018-12-10 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas turbines play an extremely important role in fulfilling a variety of power needs and are mainly used for power generation and propulsion applications. The performance and efficiency of gas turbine engines are to a large extent dependent on turbine rotor inlet temperatures: typically, the hotter the better. In gas turbines, the combustion temperature and the fuel efficiency are limited by the heat transfer properties of the turbine blades. However, in pushing the limits of hot gas temperatures while preventing the melting of blade components in high-pressure turbines, the use of effective cooling technologies is critical. Increasing the turbine inlet temperature also increases heat transferred to the turbine blade, and it is possible that the operating temperature could reach far above permissible metal temperature. In such cases, insufficient cooling of turbine blades results in excessive thermal stress on the blades causing premature blade failure. This may bring hazards to the engine's safe operation. Gas Turbine Blade Cooling, edited by Dr. Chaitanya D. Ghodke, offers 10 handpicked SAE International's technical papers, which identify key aspects of turbine blade cooling and help readers understand how this process can improve the performance of turbine hardware.

This book was released on 2012-11-27 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive reference for engineers and researchers, Gas Turbine Heat Transfer and Cooling Technology, Second Edition has been completely revised and updated to reflect advances in the field made during the past ten years. The second edition retains the format that made the first edition so popular and adds new information mainly based on selected published papers in the open literature. See What’s New in the Second Edition: State-of-the-art cooling technologies such as advanced turbine blade film cooling and internal cooling Modern experimental methods for gas turbine heat transfer and cooling research Advanced computational models for gas turbine heat transfer and cooling performance predictions Suggestions for future research in this critical technology The book discusses the need for turbine cooling, gas turbine heat-transfer problems, and cooling methodology and covers turbine rotor and stator heat-transfer issues, including endwall and blade tip regions under engine conditions, as well as under simulated engine conditions. It then examines turbine rotor and stator blade film cooling and discusses the unsteady high free-stream turbulence effect on simulated cascade airfoils. From here, the book explores impingement cooling, rib-turbulent cooling, pin-fin cooling, and compound and new cooling techniques. It also highlights the effect of rotation on rotor coolant passage heat transfer. Coverage of experimental methods includes heat-transfer and mass-transfer techniques, liquid crystal thermography, optical techniques, as well as flow and thermal measurement techniques. The book concludes with discussions of governing equations and turbulence models and their applications for predicting turbine blade heat transfer and film cooling, and turbine blade internal cooling.
Download or read book Development of Novel Tapered Pin Fin Geometries for Additive Manufacturing of Compact Heat Exchangers written by Julien Harry Cohen and published by . This book was released on 2016 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pin fin arrays are widely used to enhance forced convection heat transfer across various industries, finding application in turbine blade trailing edges, electronics cooling, and broadly for compact heat exchange. Fin shape greatly affects flow separation and turbulence generation, and optimizing performance relies on a balance between increased heat transfer and increased pressure loss along the array. Straight circular pin fins are well-characterized in the literature, and recent works have proven more complex elliptical and teardrop cross-sectional shapes to exhibit performance enhancements in both parameters. There exist few studies in the public record on tapered circular pin fins, but these have also proven to exhibit performance enhancements. To date, no example of research has been identified for tapered, complex pin fin geometries, and although these represent an avenue for overall performance gains, manufacturing the intricate components is difficult and time-consuming using conventional machining processes. The unique and nascent capabilities of additive manufacturing now allow their economical fabrication in an increasing number of fully-dense engineering materials. This thesis compares 21 fin arrays of varying fin cross-section, taper angle, taper profile, and array pattern, separated into eight geometry families. Experimental testing was carried out on a prototype open-loop wind tunnel and corroborated with computational fluid dynamics simulations. Non-dimensional metrics were defined and used to holistically compare heat transfer efficiency, pressure loss characteristics, and overall balanced performance between fin arrays. Topics for future work and potential methods of investigation are suggested.
