mixed convection flow of couple stress fluid in a vertical channel with radiation and soret effects

The radiation and thermal diffusion effects on mixed convection flow of couple stress fluid through a channel are investigated. the governing non-linear partial differential equations are transformed into a system of ordinary differential equations using similarity transformations. the resulting equations are then solved using the spectral quasi-linearization method (qlm). the results, which are discussed with the aid of the dimensionless parameters entering the problem, are seen to depend sensitively on the parameters.
