リングヒータ式蒸気流量計のシミュレーションと流量予測方法の検討

抄録

A novel flow meter using a circumferential heater, which measures the steam velocity in pipes, has been developed for performance diagnosis and energy solution in facilities such as factories and power plants. Since this flow meter can be installed from the outside of the steam tubing, it is not necessary to stop the operation of the facilities. In this study, CFD simulation that reproduces the operation of the steam flow meter was performed and a simple method for the prediction of steam velocity with the flow meter was discussed. The velocity predicted with the method showed a good agreement with the velocity measured with coriolis flowmeter.
