Abstract : An analysis has been carried out to study a problem of the heat generation/absorption and thermal radiation effects on Heat and Mass transfer in Hydromagnetic Williamson nanofluids flow over an exponentially stretching sheet in porous medium. Using appropriate similarity transformations, the governing nonlinear partial differential equations are transformed into non-linear ordinary differential equations. The transformed non-linear ordinary differential equations are then solved numerically by in built bvp4c solver package in MATLAB. The velocity profile, temperature profile and concentration profile are discussed and the influence parameters like Brownian motion parameter, Thermophoresis parameter, Thermal radiation parameter, Prandtl number, Heat source/sink parameter, Williamson parameter, Porosity parameter, Hartmann number and Lewis number are depicted graphically.
