چکیده انگلیسی
This paper deals with the investigation of double-diffusive heat and mass transfer characteristics of an oscillatory viscous electrically conducting micropolar fluid over a moving plate with convective boundary condition and chemical reaction. The non-linear partial differential equations are first converted into nonlinear ordinary differential equations by means of perturbation analysis and the governing equations are solved analytically. The effects of magnetic field, chemical reaction, permeability parameter, Prandtl number, Schmidt number, thermal radiation and viscosity parameter are analyzed on skin friction, Nusselt number, velocity, and temperature & concentration distributions. It is observed that the concentration profiles decrease with increase in the dimensionless time and increase with increase in the chemical reaction parameter. It is also observed that the velocity profile increases with increase in time but reverse effects are found by increasing the value of the viscosity ratio parameter. Further, it is seen that the effect of magnetic field parameter is to increase the micro-rotational velocity profiles but reverse effect is observed by increasing time.
