Implementation of the similarity transformations, transformed the fluid non-linear ordinary differential equations andnumericalcomputationisperformedtosolvethoseequationsusingSpectralCollocationMethod.Various pertinent parameters onfluid flow, temperature andconcentrationdistributions of the Cassonnanofluid flow as well as the local skin friction coefficient, local Nusselt number, and Sherwood number are graphically displayed. The resultsindicatethatthermophoresisparameterN_tenhancedthetemperatureandnanoparticleconcentration profiles,becauseariseinthermophoresisparameterenhancesthethermophoresis forcewithintheflowregime. Values of both local Nusselt and Sherwood numbers are enhanced with an increase in Hartman number (magnetic field parameter). The present results are compared with previously reported ones and are found to be in excellent agreement.
