Abstract:

This report is a companion volume to Cavitation Damage Mechanisms Experimental Study of Cavitation in a Spool Valve. The state-of-the-art available in the literature is reviewed relative to occurrence of cavitation, the effects of dissolved and free gas, and so-called secondary aspects of combustionsono-luminescence and electricalchemical effects. It should be noted that a paucity of literature exists with regard to cavitation in oil hydraulic systems consequently much of the material discussed deals with water as the working fluid. Throughout the text clear distinctions are made as to the fluid under discussion. The small number of references which do relate to oils are covered as thoroughly as deemed necessary. The last topic to be presented concerns cavitation in hydraulic actuators. This is a markedly different type of cavitation than is dealt with in the present experimental study it is included for completeness and due to the fact that it can be a potential problem in control system performance, although most often it creates no permanent mechanical damage to actuator components.
