Numerical Investigation on Flow and Heat Transfer Characteristics in the Natural Circulation Test Loop of Supercritical Water
The numerical simulation on both flow and heat transfer characteristics in natural circulation test loop of supercritical water under test conditions was carried out to show that,the calculated values are in good agreement with the experimental values and the maximum relative deviation of circulation flow is only 5.7%;the inner wall temperature rises slowly with the increase of heating power at the beginning and when the power is greater than about 8 kW,the inner wall temperature rises sharply and the corresponding heat transfer coefficient drops obviously.This indicates that this position stays near the pseudo critical temperature.
