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 Fin Shape Thermal Optimization Using Bejan s Constuctal Theory written by Giulio Lorenzini and published by Morgan & Claypool Publishers. This book was released on 2011-01-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains research results obtained by applying Bejan's Constructal Theory to the study and therefore the optimization of fins, focusing on T-shaped and Y-shaped ones. Heat transfer from finned surfaces is an example of combined heat transfer natural or forced convection on the external parts of the fin, and conducting along the fin. Fin's heat exchange is rather complex, because of variation of both temperature along the fin and convective heat transfer coefficient. Furthermore possible presence of more fins invested by the same fluid flow has to be considered. Classical fin theory tried to reduce the coupled heat transfer problem to a one-dimensional problem by defining an average temperature of the fin and writing equations using this parameter. However, it was shown that this approach cannot be used because of the effects of two-dimensional heat transfer, especially in the presence of short fins. CFD codes offer the possibility to consider bi-dimensional (and more generally, three-dimensional) effects and then a more real approach to the physic phenomena of finned surface's heat exchange. A commercial CFD code was used to analyse the case of heat exchange in presence of T-shaped fins, following an approach suggested by Bejan's Constructal Theory. The comparative results showed a significant agreement with previous research taken as a reference, and this result allows for the application of this approach to a wider range of systems. T-shaped optimized fin geometry is the starting point for further research. Starting from the optimal results (T-shape optimized fins), we show the trend of the assessment parameter (the dimensionless conductance) in function of the angle α between the two horizontal arms of the fin. A value for α, 90°

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first major work covering applications in thermal engineering and offering a comprehensive introduction to optimal control theory, which has applications in mechanical engineering, particularly aircraft and missile trajectory optimization. The book is organized in three parts: The first part includes a brief presentation of function optimization and variational calculus, while the second part presents a summary of the optimal control theory. Lastly, the third part describes several applications of optimal control theory in solving various thermal engineering problems. These applications are grouped in four sections: heat transfer and thermal energy storage, solar thermal engineering, heat engines and lubrication.Clearly presented and easy-to-use, it is a valuable resource for thermal engineers and thermal-system designers as well as postgraduate students.
Download or read book Contraction Heat Transfer Coefficient Correlation for Rectangular Pin Fin Heat Sinks written by Stephan Schmitt and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for smaller but more powerful electronic components is ever increasing. This demand puts a strain on engineers to produce optimal cooling designs for these electronic components. One method for cooling these electronic components is with heat sinks which effectively increase the surface area available for extracting the heat from the electronic components. Computational Fluid Dynamics (CFD) software is sometimes used to aid in the design process, but CFD simulations are computationally expensive and take long to complete. This causes the design engineer to test only a few proposed designs based on his/her experience and select the design that performs the best out of the tested designs, which might not be the optimum. The temperature distribution inside the heat sink can be solved relatively quickly with the diffusion equation, but the flow around the heat sink complicates the CFD simulation and increases the solving time significantly. Therefore, applications have been developed where the interaction between the heat sink and the flow around the heat sink is replaced by heat transfer coefficients. These coefficients are calculated from correlated equations which contain the flow properties. The flow properties are extracted from a flow network solver, which solves the flow around the heat sink. This procedure results in less expensive simulations, which can be used together with an optimisation procedure to develop an optimum cooling design. In this dissertation, a correlation for the contraction heat transfer coefficients of rectangular pin fin heat sinks was developed. A methodology was developed where consecutive regression lines were fitted to a large set of data extracted from numerous CFD simulations. The combination of these regression lines formed the basis of the correlation, which was divided into two correlations: one for laminar flow and another for turbulent flow. The correlations were tested against CFD simulations as well as experimental data. The results indicate that these correlations can be effectively used to calculate the contraction heat transfer coefficients on pin fin heat sinks.
