Influences of Stefan blowing on unsteady flow of Casson nanofluid past a stretching surface

Abstract

This paper deals with the flow of non-Newtonian nanoliquid past an unsteady stretched exterior in attendance of Stefan blowing/suction. Model for Casson liquid has been taken into account to represent the non-Newtonian liquid. Two phase fluid replica for nanofluid has been considered. Similarity alterations are applied to transform the leading pdes (partial differential equations) to ordinary ones. Runge–Kutta method of order four has been used to solve the altered equations numerically with the help of shooting technique. Wall shear stress, heat and mass transfer coefficients diminish with the rise in unsteadiness. Fluid's velocity and temperature are found to rise with the enhancement in Stefan blowing/suction parameter. Temperature of the fluid rises but fluid's velocity diminishes for the rising values of Casson parameter. Basically, the pertinent parameters affect the stream, warmth and accumulation transport significantly which can be viewed by the figures and tables presented here and also by their physical analysis.
