The irregular grid finite-volume method is proposed for computation of heat transfer and fluid flows in complex region.The efficient strategies for overcoming some difficulties,which include implementation of hybird convection schemes,maintain of diagonal dominance and treatment of pressure correction equation,are presented.Comparing the results with other numerical results available in the literature the proposed algorithm shows that it has higher accuracy.
