Study of unsteady casson nanofluid flow across a stretching surface embedded in a porous medium in presence of stefan blowing and radiation
摘要
This paper addresses non-Newtonian nanofluid flow when Stefan blowing/suction is present past an unstable stretched exterior. The non-Newtonian liquid has been represented by considering the Casson liquid model. Consideration has been given to a two-phase fluid replica for nanofluid. The leading partial differential equations are converted to ordinary ones using similarity modifications. With the use of the shooting approach, the updated equations have been numerically solved using the Runge–Kutta method of order four. As unsteadiness increases, wall shear stress, coefficients of heat, and mass transport. The fluid temperature and velocity are observed to increase when the Stefan blowing/suction parameter increases. The fluid temperature increases and its velocity slows as the Casson parameter values increase. Coefficient of skin friction is growing function of Stefan blowing parameter
