Abstract

Abstract: Based on changes in steam compression refrigeration system of export cross-sectional area of the conventional method of throttling jet noise and can effectively inhibit the throttle device sudden noise, according to the ring bubble flow system contributes to the stability of the two phase flow, using mixed steam unit build super cavitation system to curb the throttling jet noise, the prospect of cavitation are introduced and the research progress of ultra-cavitation noise, the proposed steam mixed noise in the throttling injection system, the application of technology, to build a throttle valve outlet ring bubble flow state, thereby inhabiting the throttling jet noise of refrigeration equipment.

Key words: Throttling noise, Vapor-doped super cavitation, Noise suppression, Research prospect
