Abstract:

An experimental investigation of the supercavitating flow around a plane hydrofoil equipped with a jet-flap at the trailing edge was carried out in a water tunnel in which the working section has rigid walls. Results are presented for a range of cavitation numbers between 0.3 and 1.2, and for jet momentum coefficients up to 0.5. The pressure forces exerted on the model were calculated from the measured distributions of static pressure on the surface of the model. The effect of the jet-flap on the pressure force at large volues of cavitation numbers is seen to be much less than that predicted by the linearized theory of Ho for zero cavitation number. Author
