Effects of chemical reaction and activation energy on Marangoni flow, heat and mass transfer over circular porous surface

Abstract

AbstractEffects of heat generation, chemical reaction and activation energy on Marangoni flow, heat and mass transfer over a circular porous surface are investigated. The problem has been formulated in the form of the nonlinear system of PDEs, which are changed to the dimensionless set of ODEs using the similarity replacement. The problem is solved numerically by a method named Legendre–Galerkin. The influences of the different parameters on the velocity, temperature and concentration are discussed and analysed. The local skin friction, local Nusselt number and local Sherwood number are also computed and investigated for different embedded parameters in the problem statements.
