Three areas of practical interest relating to flow in valves are addressed: cavitation, flow-induced vibration and noise. Such conditions are common when pressure drop across the valves is high and result in unsatisfactory behavior of the systems. Valve industry background in each of these areas is discussed briefly. The success in eliminating cavitation in valves is described. Reliable quantitative prediction of vibration and noise in valves is still a formidable challenge. Experimental work to understand some of the fundamental mechanisms in these two areas is presented.
