This paper deals with an experimental study on the suppression method of the cavitation in a cylindrical choke for the steady and unsteady flows. The test of the suppression methods was performed for the two-stage choke. Experiments for the unsteady flow were carried out under a condition in which inlet pressure p1 in the cylindrical choke tests a trapezoid form with time, while keeping the outlet p2 constant. The pressures of four locations in these tests were measured with a pressure transducer at the same time for various unsteady flows. Moreover, a camera took the cavitating pictures for the steady flow. As a result, the method placed the two-stage choke was a good method for the suppression of cavitation.
