Abstract

A theoretical analysis performed for investigating steady boundary layer flow of convective conditions on magnetohydrodynamic flow over stretched cylinder with time dependent heat source/sink. Proposed mathematical model has a tendency to characterize the effect of magnetohydrodynamic flow over stretched cylinder wit time dependent heat source/sink. The non-linear ordinary differential equations are solved using the Runge-Kutta method. The characteristics of velocity and temperature boundary layers for different physical parameters such as Biot number Bi, Reynolds number Re, space dependent A* and temperature dependent heat source/sink B*, Weissennberg numberWe over the non-dimensional velocity and temperature profiles are presented graphically in absence (K  0) and presence (K  0.5) of porosity parameter. Moreover, the local friction factor coefficient, Nusselt numbers are also estimated and discussed for aforesaid physical parameters.
