The Numerical Solution of the Unsteady Natural Convection Flow in a Square Cavity at High Rayleigh Number Using SADI Method

  • The unsteady natural convection flow in a square cavity at high Rayleigh number Ra=107 and 2×107 has been computed using cubic spline integration. The required solutions to thetwo dimensional Navier-Stokes and energy equations have been obtained using two alternate numerical formulations on non-uniform grids. The main features of the transient flow have been briefly discussed. The results obtained by using the present method are in good agreement-with the theoretical predictions[1,2]. The steady state results have been compared with accurate solutions presented recently for Ra=107.
