Physically-Based Models for Two-Phase Flow Phenomena in Steam Injectors : A One-Dimensional Simulation Approach (KIT Scientific Reports ; 7704)

Simulation models for the two-phase condensing flow in steam injectors are presented that allow determination of major flow parameters on a physically sound basis. The investigated phenomena are spontaneous condensation during steam expansion, gas dynamic jet adaptation, and direct contact condensation of steam jets. The simulation results are in good qualitative agreement with experimental data over a wide parameter range without the need for adaptation to specific experimental conditions.
