An Experiment on Cavitating Flow in Rocket Engine Inducer

摘要

An experiment for rocket engine inducer cavitating flow is conducted on a new experimental platform. The experiment platform,using water as working medium,can be used to investigate the steady and unsteady flows of cavitating and noncavitating turbopumps. The experimental platform is designed as a flexible and versatile apparatus for any kind of fluid dynamic phenomena relating to high performance liquid rocket engine turbopumps. Design details for the platform is introduced. Various extend of cavitation images and dynamic pressure impulse are obtained,which provides a reference for cavitating flow study in rocket engine inducer.
