Abstract

Irreversibility phenomenon is numerically investigated for mixed convection flow along a uniformly heated vertical wavy surface. Surface texture of the plate does not allow for a self-similar solution due to which the nature of the problem is non-similar. The numerical solution of the governing non-similar equations has been achieved by utilizing the implicit finite difference scheme commonly known as Keller-Box method and the outputs are shown through graphical pictures. The influence of various physical parameters of interest (mixed convection parameter, wavy amplitude, Prandtl number) on entropy generation and Bejan number has been discussed in detail. It is observed that entropy production enhances with an increment in mixed convection parameter.
