Symmetric Cavitation Flow around a Cylinder with a Point Effluent on Its Surface

Abstract

The problem of a symmetric stationary cavitation flow around a cylinder by an infinite flow of ideal incompressible weightless fluid in the presence of a given intensity point effluent located at the front point of the cylinder is considered. The exact solution to the problem is constructed by mapping the areas of change in the complex potential and complex flow velocity onto the area of change in the auxiliary parametric variable. A parametric analysis of the problem is performed. For a wide range of values of the cavitation number, the dimensionless flow rate, the shape and dimensions of the cavitation cavity, and the values of the drag coefficient are found.
