Experimental Study on Over Reading Coefficient in Wet Steam Flow Measurement

CNNC Key Laboratory on Nuclear Reactor Thermal Hydraulics Technology, Nuclear Power Institute of China, Chengdu, Sichuan, 610041, China

摘要: 加工不同喉径的文丘里流量计开展湿汽流量测量系统的实验研究,对一定工况参数范围内不同干度、流量的湿蒸汽流量进行实际测量。分析压力、L-M(Lockhart-Martinelli)参数、质量流量、喉径比对虚高系数的影响特性。
