Natural convection in a micropolar fluid with thermal dispersion and internal heat generation

A similarity solution is presented for the flow of a micropolar fluid along an isothermal vertical plate with all exponentially decaying heat generation term and thermal dispersion. Numerical solutions are obtained for the governing equations. Results for velocity, angular and thermal functions are displayed for a range of values of the material parameters of micropolar fluid and thermal dispersion parameters. The data for friction factor, Nusselt number and wall couple stress have been tabulated for a range of thermal dispersion parameters s, Prandtl numbers Pr and micropolar parameter Delta.
