UNSTEADY FREE CONVECTION FLOW WITH FLOW CONTROL PARAMETER

The unsteady incompressible free convection boundary layer equations in two dimensions, with heat transfer have been solved numerically using finite difference method. The unsteady free convection flow with flow control parameter effect is presented in this work. The governing second order differential equations are derived from the fluid motion (Navier-Stokes equation) and heat conduction (energy equation) equations. Mathematical formulation of boundary layer equations have been non-dimensional zed by using dimensionless variables. These non-dimensional boundary layer equations are non-linear and partial differential equations and are solved by finite difference method. The fluid particles such as air ?P r ? 0.71?, water at 200 C ?P r ? 0.70? and salt water ?P r ?1.0? are considered. In different Eckert numbers and for various Grashoff numbers as well as Prandlt numbers, the results of velocity and temperature are displayed in the form of level curves for both the temperature and velocity function.
