Computer simulation of supercavitating body dynamics (English)
0 references
A method of theoretical investigation of global stability of high-speed supercavitating motion by direct computer simulation is proposed. The mathematical model is based on the principle of independent cross-section cavity expansion and takes into account hydrodynamic interaction with inner cavity walls. A brief outline of the software is given. Computer simulation confirms the possibility of self-stabilization of supercavitating bodies by ricocheting their tail from inner cavity walls. In experiments the action of this self-stabilization mechanism exhibits periodic perturbations of the cavity surface. This effect is named here high-speed shooting.
