• EFFECT OF HEAT SOURCES ON NON-DARCY CONVECTIVE HEAT AND MASS TRANSFER FLOW OF NANOFLUIDS IN CYLINDRICAL ANNULUS

W e analyze non-Darcy convective heat and mass transfer flow of nanofluids in a cylindrical annulus with heat sources and chemical reaction. By employing Galerkin finite element analysis with quadratic approximation functions the governing equations have been solved. The velocity, temperature and concentration have analyzed for G, D -1 , D , α, g , Sc and f . Also the Skin friction and the rate of heat and mass transfer have been obtained for different parametric variations. It is found that the velocity and actual concentration reduces with increase in heat generating source and enhances with heat absorption source, while the temperature reduces with heat generating/absorption source.
