This paper attempts first to predict theoretically the influence on the nonsteady pressure perturbations on a blade row as a result of periodic wakes shed from an upstream blade row, and then to compare such theoretical predictions with a series of carefully conducted cavitation experiments at the Garfield Thomas Water Tunnel of the Ordnance Research Laboratory. The results indicate that the experimental values of pressure perturbations are somewhat lower than theoretically predicted values. The general trend, e.g., the influence of wake width and wake spacing, is in substantial agreement between theory and experiments.
