Abstract:
Purpose: The purpose of this paper is to analyse the force convection laminar boundary layer flow on irregular boundary in diverging channel with the presence of magnetic field effects. Effects of various fluid parameters such as suction/injection, viscous dissipation, magnetic parameter and heat source/sink on velocity and temperature profiles are numerically analyzed. Moreover, numerically investigated on skin-friction and heat transfer coefficients when suction/injection occur. Design/methodology/approach: The governing coupled partial differential equations are transformed to dimensionless form using non-similarity transformations. The non-dimensional partial differential equations are linearized by quasi-linearization technique and solved by vargas algorithm with numerical finite difference scheme on a non-uniform mesh.
Keywords:
Coupled partial differential equation; Finite difference scheme for non uniform mesh; MHD flow; Quasilinearization; Wall suction/injuction
