Abstract

The transient flow behavior in the oxygen dome of the HM7 engine has been experimentally modelled with a pressurized, heated water flow. The evolution of the inlet mass flow rate and the dome pressure distribution was measured and correlated with flow visualization results of the internal flow and the outflow. Driving pressures, fluid temperature, and purge flow conditions were varied during the course of the experiments. Comparison with available liquid oxygen test results showed good agreement and confirmed that such water rests are a valuable tool in characterizing the flashing flow into the oxygen dome. Such data is needed for the design of the ignition system and the selection of the optimum ignition sequence.
