1. It is noted that the mass flows for the point Convection operator are defined as positive leaving the upwind local control volume to the surface being considered. For further details of the positive coefficient, skewed and advanced skew upwind schemes, see References 16-19 and 21,Raw and Schneider.
2. As can be seen from these figures the Present predictions are in excellent agreement with the experimental data and that convective energy transport plays a significant role in the transport of energy. A AFo = 1 was used to obtain the transient evolution and this meets the previously stated criterion for temporal accuPacy of STE'AFO - 10-4 given by Schneiderl 0.4 in diffusion dominated problems.
