There are many parameters that affect the natural circulation flow, such as height difference, heatingpower size, pipe diameter, system pressure and inlet temperature and so on. In general analysis theheating power is often regarded as a uniform distribution. The ANSYS-CFX numerical analysis softwarewas used to analyze the flow heat transfer of supercritical water under different heating power distributionconditions. The distribution types of uniform, power increasing, power decreasing and sinefunction are investigated. Through the analysis, it can be concluded that different power distribution hasa great influence on the flow of natural circulation if the total power of heating is constant. It was foundthat the peak flow of supercritical water natural circulation is maximal when the distribution of heatingpower is monotonically decreasing, minimal when it is monotonically increasing, and moderate atuniform or the sine type of heating. The simulation results further reveal the supercritical water underdifferent heat transfer conditions on its flow characteristics. It can provide certain theory reference andsystem design for passive residual heat removal system about supercritical water.
