摘要：

Two-phase flashing flow methods used by DIERS, the American Petroleum Institute (API) and ASME are reviewed and compared. For saturated and low quality inlet conditions, the API method was found to yield higher theoretical mass flow rates than the DIERS homogeneous equilibrium flow model (HEM). The degree of disparity can be quantified by two dimensionless physical property groups. Comparison with flashing flow data for water, refrigerant 12 and a propane-butane mixture shows good agreement with the HEM prediction, but poor agreement with the API method. The ASME method only recommends a saturated water flashing flow curve that is in agreement with the HEM calculation to within 10%. © 1990.
