摘要：

It's difficult to measure the flux of supercritical water because of its high temperature and pressure. With a example of supercritical water with a pressure of 25 Mpa in tube (inner diameter = 37 mm), experiments and simulation were taken to study the mass flux measurement by orifice flowmeter. At normal atmosphere, the orifice plate is demarcated by weighing method, and then simulated by Fluent software, so the reliability of simulation can be checked. At supercritical pressures, a series of conditions with different temperatures and pressures were simulated by Fluent software, and then characteristics of the orifice discharge coefficient were studied.
