Water Turbopump Inducer Performance with and without a Stability Control Device

Salt Lake Community College Student Center

Operating conditions for a turbopump are often limited by the inducer. Extreme operating conditions can cause an inducer to fail. This paper explores the effect that a stability control device has on the performance of an inducer with and without the presence of cavitation. Numerical studies performed show that the head rise through the inducer is about the same for all cavitation numbers but the radial loads on the inducer are significantly less when a stability control device is incorporated.
