Experimental Study of Mixed Convection Heat Transfer Using Circular, Square, Rhombic Fins

Pulling Fins are extended surfaces employed to enhance the convective heat transfer from a surface for increasing heat dissipation. Fins with various geometries have been designed and used in various cooling application the selection of particular fins configuration in any heat transfer application is an important state in designed process and takes into account the space, weight, manufacturing technique and cost consideration as well as the thermal characteristics it exhibits. Fins cross section profiles have profound influence on thermal characteristics of Annular Fins and the surface area changes with change of cross section of fins. This study deals with studying the performance of various available fins profiles. Widely used fins profile viz. Rectangular, Triangular, Trapezoidal, Circular, Rhombic, and Elliptical Fins. In Addition to the normal configuration of fins, to new configurations were designed and created

Experimental Study of Heat Transfer From Plate Fin Array in Mixed Convection Mode

The work summarized in this paper presents an experimental study of heat transfer from plate fin in mixed convection mode enhancement by the use of plate fins is presented. After a brief review of the basic methods used to enhance the heat transfer by simultaneous increase of heat transfer surface area as well as the heat transfer coefficient, a simple experimental method to assess the heat transfer enhancement is presented. The method is demonstrated on plate fins as elements for the heat transfer enhancement, but it can in principle be applied also to other fin forms
