STUDY AND ANALYSIS OF THE CAVITATING AND NON-CAVITATING JETS - PART ONE: PARAMETERS CONTROLLING FORCE, POWER AND THE JET BEHAVIOR

ABSTRACT
This paper presents the dependency of the jet power and the cavitation intensity on the working conditions of the cavitating and non-cavitating jet flow. This dependency is indicated by the cavitation erosion process and flow structure. The effects of working conditions on the cavitation erosion were experimentally investigated. The flow visualization was done using a high-speed photography recording system. The analysis shows that the erosion rate calculation and the visualization of the jet structure can be used as tools to estimate the jet strength, the jet actions, the jet power, and the performance of the jetting system.
