NUMERICAL SIMULATION OF ROTATING CAVITATION IN A LIQUID OXYGEN PUMP INDUCER

摘要：

An inducer as a key component raises suction performance of liquid propellant rocket engine pump.It can operate under low pressure condition, and cavitation is inevitable.But the developments of rotating cavitation which due to cavitation can seriously degrade the performance of the turbopump, or even cause its rapid failure.Based on the mixture multiphase model, simulation of rotating cavitation in a two-cascade drawn from the liquid oxygen inducer geometry was carried out.The results indicate that a super-synchronous rotating cavitation with propagation speed ratio is approximately 1.1N, and variable pressure on the two blades leads to it takes place.
