Analytical expressions of the effect of radiation on free convective flow of heat and mass transfer
This paper deals with the effect of mass and radiative heat transfer on free convective flow of a viscous incompressible optically thick fluid towards a vertical surface has been investigated. The nonlinear non-dimensional, similarity-transformed boundary-layer equations of the problem are solved analytically. The resulting equations are solved analytically by using Homotopy analysis method. The velocity field, temperature field and concentration distribution have been discussed and the analytical results are presented graphically. This type of problem is significantly relevant to geophysical and astrophysical studies.
