Galerkin Method of Weighted Residual to Study on Enhanced Heat Transfer in Cylindrical Micro-Fins Heat Sink Using Artificial Surface RoughnessBy Gbeminiyi Musibau Sobamowo, K. F. Dukor, G. A. Oguntala
Abstract: In this paper, a theoretical investigation is carried out on the use of artificial surface roughness for enhanced heat transfer and thermal management of cylindrical micro-fins with artificial surface roughness. The developed thermal models which are solved using Galerkin method of weighted residual, considered variable thermal properties according to linear, exponential and power laws. The approximate analytical solutions are used to carry out parametric studies and to establish the thermal …
