Abstract

The effect of mass diffusion and radiation absorption on MHD pulsatile flow of some Non Newtonian nanofluids was analysed. The influence of viscous dissipation, heat source, thermal radiation, radiation absorption and Schmidt number are accounted. For this study, we considered Eyring Powell nanofluid and Casson nanofluid. Similarity transformations are used to convert the governing partial differential equations into ordinary differential equations and then solved analytically using perturbation technique. The physical parameters impacts on velocity, temperature and concentration profiles are studied using graphs. It is worthwhile to observe that intensifying value of Radiation absorption parameter appreciates temperature profiles whereas depreciates concentration profiles. The results are presented and discussed comparatively for both Eyring Powell nanofluid and Casson nanofluid.
