摘要

The present article is concerned with the unsteady squeezing flow of non-Newtonian nanoliquid between the two parallel plates. A rheological relation of second grade liquid is utilized. Thermal radiation, Brownian motion and thermophoretic diffusion are retained. Second grade liquid is electrically conducted subject to time-dependent magnetic field. The induced magnetic field is neglected for small magnetic Reynolds number. Suitable transformations yield the strong nonlinear ordinary differential system. The resulting nonlinear system is computed. Intervals of convergence in the series solutions are explicitly determined. Velocity, temperature and concentration fields are graphically analyzed. Skin friction coefficient and local Nusselt and Sherwood numbers have been numerically tabulated and examined. It is observed that the temperature and concentration distributions are enhanced for larger values of Brownian motion parameter. Moreover the Lewis and Prandtl numbers have similar behaviors for concentration distribution.
