Possible Schemes of Cavity Closure.

Two new schemes of incompressible inviscid steady-state symmetric (circulationless) cavitation flow are considered. In these schemes the cavity is closed on a flow domain bounded by a closed streamline encircling either a dipole or twin point vortices with circulations equal in magnitude and opposite in sign. A comparative analysis of the efficiency of applying these schemes is performed for the case of transverse flow past a flat plate. On the cavitation number range 0.01 ≤ \sigma ≤ 0.15 the drag coefficient and the relative cavity diameter and length obtained in this study are compared with their values calculated from the Riabouchinsky and Efros schemes. For a particular value of the cavitation number, the shapes of the cavities are also compared. The solutions obtained possess the properties of univalence and closure and satisfy the Brillouin condition. [ABSTRACT FROM AUTHOR]
