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 tests of the suppression methods were performed for the two-stage choke and the choke with the orifice at the outlet of the single-stage choke. Experiments for the unsteady flow were carried out under a condition in which inlet pressure p_1 in the cylindrical choke takes a trapezoid form with time, while keeping the outlet p_2 constant. The pressures of four locations in these were measured with a pressure transducer at the same time for various unsteady flows. Moreover, the cavitating pictures for the steady flow were taken by a camera. It was found that the choke with the orifice in the outlet at the single-stage choke is a good method for the suppression of cavitation.
