The FLUENT, which is a commercial computational fluid dynamics software, and the volume of fluid multiphase flow model were used to simulate the two-phase flow in a steam−water mixing heater. The condensation heat transfer source term and the mass transfer source term, which were obtained by calculating the phase interface temperature gradient, were integrated in the simulation. The simulation results coincide with experimental data and show that the exit speed, temperature, and the nondimensional length of the steam plume increase with increasing inlet steam pressure. %8 2015-08-04
