Optimum Length for Pin Fins Used in Electronic Cooling

Abstract: The present work deals with the heat transfer analysis of pin fins of various geometries namely ─ circular, triangular and rectangular and thus arrive at the optimum design. To this end, the fin with convective boundary tip is considered and the equation governing the one-dimensional heat conduction in the fin is solved analytically to obtain the temperature distribution and heat transfer rate. A computer code has been developed to generate results for wide range of parameters─ heat transfer coefficient h, thermal conductivity k, and length of the fin l. Results are plotted in the form of temperature variation, heat transfer variation and optimum length variation. From the detailed discussion of the results it can be concluded optimum length decreases with increasing heat transfer coefficient and it increases with increasing thermal conductivity. It can be also concluded that the optimum length is minimum for a triangular fin compared to rectangular and circular fins.

Numerical investigation on heat transfer characteristics of a nuclear fuel rod

Abstract: This paper deals with the numerical prediction of thermal performance characteristics of a cylindrical nuclear fuel element having nonuniform energy generation in axial direction. Accordingly, the two-dimensional heat conduction equation having a cosine variation of heat generation term in the axial direction, along with appropriate boundary conditions is solved using second order accurate finite difference schemes. The discretized equations in the form suitable to Line-by-Line method of solution procedure are solved employing the famous ‘Thomas Algorithm’ using an indigenously developed C code. The results are presented for a wide range of parameters - Aspect Ratio, A r , Biot number, Bi and total heat generation parameter, Q t in the form of comparison of the temperature profiles and maximum temperature for uniform and nonuniform energy generation. From the detailed discussion of the results it is concluded that, the maximum value of temperature attained in the fuel element for nonuniform volumetric energy generation is much higher than that of uniform volumetric energy generation. Also the non-uniform volumetric energy generation demands higher rate of energy dissipation from the surface of nuclear fuel element which is related to pumping power requirement of the coolant.
