Theoretical Investigation of MHD Nanofluid Flow Over a Rotating Cone: An Optimal Solutions

The problem of MHD nanofluid flow over a rotating cone in the presence of thermal radiation has been investigated. The model used for the nanofluid includes the effects of Brownian motion and thermophoresis with Rosseland diffusion approximation. The governing nonlinear partial differential equations have been treate d analytically by using optimal homotopy analysis method. A parametric study of various emerging parameters are presented for velocity, temperature, nano particle volume fraction, Skin friction coefficients, Nusselt and Sherwood numbers in graphical and tabular form. The comparison of present results with the numerical results available in literature is made and our results are in very suitable agre ement with the known results. Also, the main features of the observations are examined and deliberated.
