Natural convective flow of hydromagnetic heat generating fluidflow through a vertical channel with time-periodic boundary conditions

Abstract

The effect of viscous dissipation and heat generation on unsteady natural convective hydromagnetic fluid with time dependent boundary conditions in a porous vertical channel was investigated. The coupled nonlinear partial differential equations governing the fluid flow and heat transfer were transformed into system of dimensionless coupled nonlinear ordinary differential equations. Differential transform technique (DTM) was used to solve the obtained dimensionless coupled nonlinear ordinary differentials equations. The effects of parameters such as suction/injection, Strouhal number, Hartmann number and heat generation/absorption parameterson the fluid temperature and velocity were presented graphically and discussed.
