| Abstract: | This paper analyzes the applicability of measuring mass flow of low pressure saturated steam in nuclear seawater desalination with a vortex shedding flowmeter (VSF) by using the homogeneous flowing model of steam-liquid two-phase flow.It discusses the relationship between the error of measuring mass flow of low pressure saturated steam with a VSF and the steam dryness based on the thermal physical characteristics of the low pressure saturated steam.It also gives out a variable coefficient density compensation formula used for measurement of mass flow of the low pressure saturated steam,and the features of this formula. |
