Download or read book Temperature Distribution and Heat Flow in Cylindrical Fin with Heat Source written by Mohamad Azman Poniran and published by . This book was released on 2012 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fin is used to increase heat transfer from heated surface to air. Industrial experience has shown that for same surface area, the fin array can transfer considerably more energy than single fin. Analysis of single fin is well known. However, when fins are placed in an arrangement, the convective patterns become consistent and the resulting heat transfer coefficient has not been predicted. The purpose of this project is to study the effectiveness of staggered cylindrical fin array with and without additional fin. Experimental data from the study is used to obtain the resulting heat transfer coefficient. The experimental study has been carried out through experiment by natural convection using test bench. The additional fin made from aluminum and fabricated in plate shape first before attach with staggered cylindrical array. From the measurement and experiment result, it shows the value of heat transfer coefficient for cylindrical array with additional fin is higher more than fifty percent compare to without additional fin. The relation of Nusselt number with heat transfer has been shown through the experimental result. The experimental result indicates that a staggered cylindrical fin array with additional fin performs better in heat transfer than staggered cylindrical fin array without additional fin. It showed that the additional fin affect the heat transfer much.

This book was released on 1961 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general differential equation of a thermally radiating fin is presented for the situation of a uniform heat source along the base of the fin. An electronic analog solution of a fin of non-uniform thickness with one-dimensional steady-state radiant heat transfer is presented. The specific example is concerned with a constant rate of variation of thickness; however, any general configuration could be used.

Download or read book Thermodynamics In Nuclear Power Plant Systems written by Bahman Zohuri and published by Springer. This book was released on 2015-04-20 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the fundamentals of thermodynamics required to understand electrical power generation systems, honing in on the application of these principles to nuclear reactor power systems. It includes all the necessary information regarding the fundamental laws to gain a complete understanding and apply them specifically to the challenges of operating nuclear plants. Beginning with definitions of thermodynamic variables such as temperature, pressure and specific volume, the book then explains the laws in detail, focusing on pivotal concepts such as enthalpy and entropy, irreversibility, availability, and Maxwell relations. Specific applications of the fundamentals to Brayton and Rankine cycles for power generation are considered in-depth, in support of the book’s core goal- providing an examination of how the thermodynamic principles are applied to the design, operation and safety analysis of current and projected reactor systems. Detailed appendices cover metric and English system units and conversions, detailed steam and gas tables, heat transfer properties, and nuclear reactor system descriptions.

Available in PDF, EPUB and Kindle. Book excerpt: In this textbook, the author teaches readers how to model and simulate a unit process operation through developing mathematical model equations, solving model equations manually, and comparing results with those simulated through software. It covers both lumped parameter systems and distributed parameter systems, as well as using MATLAB and Simulink to solve the system model equations for both. Simplified partial differential equations are solved using COMSOL, an effective tool to solve PDE, using the fine element method. This book includes end of chapter problems and worked examples, and summarizes reader goals at the beginning of each chapter.

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°
