Using Constant Slip Ratios to Model Non-Flashing (Frozen) TWo-Phase Flow Through Nozzles

The TPHEM computer program, supplied with the recently published AlChE / CCPS book "Guidelines for Pressure Relief and Effluent Handling Systems", can be used to reproduce a range of two-phase flow data through nozzles. The ability to predict data and design emergency relief systems using simple models is important to the practicing engineer.
