N2 - A simple computer program has been developed for calculating homogeneous choked two-phase flow through pipes. Its predictions have been compared with results of vessel blowdown experiments with freon-12 and water. These comparisons not only relate to the rate of discharge, but also comprise pressures and temperatures in the discharge pipe. Special attention has been paid to the temperature measurements. Differences existing between predictions and experiments could be indicative of a pronounced role of thermodynamic disequilibrium phenomena. The effect of some elementary assumptions concerning superheat, nucleation delay and relaxation to equilibrium has been investigated. In addition, the effect of varying the value of the friction coefficient has been examined.
