Résumé

In the article the problem of a symmetric stationary cavitation flow around a wedge by an infinite flow of ideal incompressible weightless fluid in the presence of a given intensity point effluent located at the top of the wedge is considered. To schematize the flow in the aft part of the cavity the Efros scheme with a return stream going to the second sheet of the Riemannian surface is used. The exact solution of the problem is constructed by displaying the areas of change complex potential and complex flow velocity per area change of the auxiliary parametric variable. A complete parametric analysis of the problem has been carried out. For a wide range values of the cavitation number, dimensionless flow rate and angle wedge solution, the shape and dimensions of the cavitation cavity are found, and See also the values of the drag coefficient. The shape and dimensions of the cavitation cavity and also the values of the resistance coefficient are found for a wide range of cavitation number values, dimensionless consumption of effluent and opening angle of the wedge.
