Flow past an impulsively started vertical plate with constant heat flux and mass transfer

Finite-difference solution of the transient natural convection flow of an i ncompressible viscous fluid past an impulsively started semi-infinite plate with constant heat flux and mass transfer is presented here. The Velocity profiles are compared with exact solution and are found to be in good agree ment. The steady-state velocity, temperature and concentration profiles are shown graphically. It is observed that there is a rise in the velocity due to the presence of a mass diffusion. The local as well as average skin-fri ction, Nusselt number and Sherwood number are shown graphically.
