Description

On the basis of supercritical water natural circulation test bench, using ANSYS CFD software, the computational fluid dynamics simulation calculation were carried out. Through the calculation the trend of the natural circulation rate and the heat transfer coefficient (HTC) with the change of the heating power was got. With the increase of the heating power, the mass flow and HTC increase gradually. Then the mass flow and the HTC reach a peak value. Since then, with the increase of power, natural circulation flow rate and HTC reduced gradually. The heat transfer and flow went into the density wave instability state. When the mass flow and HTC are approaching the peak value, the heater outlet temperature is close to the pseudo-critical temperature. Through the contrast of the numerical simulation results with the experiment, comparative results are in good agreement. (authors)
