A Numerical analysis is performed to study the effect of Thermophoresis on steady mixed convective boundary layer flow of a rotating fluid over a rotating vertical cone in a non - Darcy porous medium. The governing boun dary layer equations are formulated and numerical results are obtained by employing shooting technique. The present numerical solutions are compared with earlier existing results and good agreement has been obtained between existing results. Numerical resu lts for fluid flow characteristics, fluid velocities (tangential, circumferential and normal), temperature and concentration distributions as well as tangential and circumferential skin friction coefficients, Nusselt number and Sherwood number are presente d graphically and discussed for different values of physical parameters such as inverse Darcy parameter, Forchheimer parameter, ratio of angular velocities, relative temperature parameter and thermophoretic coefficient. Increasing Forchheimer parameter ret ards tangential skin friction coefficient, Nusselt number and Sherwood number but enhances circumferential skin friction coefficient. As increase in ratio of angular velocities tangential and circumferential skin friction coefficients are increased but Nus selt number and Sherwood number results are reduced. The wall thermophoretic velocity profile increases with increasing values of Forchheimer parameter and ratio of angular velocities and with decreasing values of relative temperature parameter.
