This book was released on 2018-08-16 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: In modernization, heat sink plays a key role to enhance heat transfer. A heat sink is a device which helps to dissipate the heat from heated surface using direct contact or radiant thermal contact. Heat sinks are basically used to enhance the heat transfer from the heated surface to eliminate the effect of overheating or burning. The heat sinks made up of copper and aluminum and directly attached to the heated surface. Extended surfaces are commonly used to improve the heat transfer in many industries. The extended surface of heat sink helps to increase the surface area in contact with air. It maintains the thermal stability of the system in limits for every electrical and electronic component of any system. There are different kinds of heat sink with different fin geometries and operating with natural or forced convection. Most of the work has been done on rectangular pin fin and circular pin fin under natural and forced convection. In present work, the modeling and fabrication is done on elliptical heat sink and perforated elliptical heat sink with circular perforation. In this work different wattages (100, 150, 200 and 250 W) are used with Reynolds number ranging from 8400 to 21000. The various flow velocities used are 4m/sec, 6m/sec, 8m/sec and 10m/sec. The perforation is done in the middle of the pin fin to achieve maximum heat transfer. The overall performance of the pin fin heat sink is affected by the perforation. In present study the experiment analysis is performed w.r.t the heat transfer coefficient, temperature variation and nusselt number for heat sinks. In experiment the working fluid is used as air. In the present work two different arrangements: elliptical pin fin heat sink and perforated elliptical pin fin heat sink are selected. Within the Reynolds number range 8400 to 21000 perforated elliptical pin fin heat has higher heat transfer coefficient in comparison to elliptical pin fin heat sink. The temperature variation in perforated elliptical pin fin heat sink is more as compare to other one. It was observe that the Nusselt number is directly proportional to the number of perforations. As the number perforation or perforation size increases the heat transfer coefficient also increases.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with certain aspects of material science, particularly with the release of thermal energy associated with bond breaking. It clearly establishes the connection between heat transfer rates and product quality. The editors then sharply draw the thermal distinctions between the various categories of welding processes, and demonstrate how these distinctions are translated into simulation model uniqueness. The book discusses the incorporation of radiative heat transfer processes into the simulation model.
