Abstract
Critical flow behavior of steam-water mixtures through orifices was investigated experimentally. As the stem quality increases, mass flow rates per unit orifice area rapidly decrease even at low pressure ratios. For the steani quality larger than 6 %, two-pliase flow shows critical flow behavior. Effects of the orifice diaineter on two-phasc flow are sinall, while an increase in the plate thickness largely depresses the inass flow rate.
