On the Calculation of Surface Pressure Distribution on a Waterjet Inlet

Abstract

In order to determine a two-dimensional cavitation free shape of a waterjet inlet, the computational method for one is given by making use of a boundary element method. Further, the contraction effect of a inlet by boundary layer displacement thickness is taken into account. This method enables us easily to obtain a cavitation free shape by trial and error procedure. Numerical examples are shown and it is suggested that the flow contraction by boundary layer thickness might be taken into account.
