Waterjet Intake 유도관 성능시험법 개발

Abstract

In order to develope the intake-diffuser with good performance for the waterjet propulsion system, new experimental device was designed and manufactured. The experimental device is installed on the test section of the KRISO cavitation tunnel. The efficiency of the intake-diffuser is calculated using the measurement result of 1-hole and 5-hole pitot tubes. The calibration of the 5-hole pitot tubes is conducted at the cavitation tunnel. The cavitation inception occurs at the intake lip, and the occurrence position depends on IVR (Inlet Velocity Ratio) condition. The present test device will be applied sufficiently for the development of the design and perfomance analysis methods.
