Semko A. Impulsive and undulatory motion of liquid with moving boundaries.

The thesis dedicated to theoretical and experimental investigation of impulsive and undulatory motion of ideal compressible liquid with moving boundaries. Mathematical models for hydroimpulsive installations and technological processes are developed. Reliable and effective numerical methods for calculation of unsteady liquid flow with cavitation are developed and adapted. A series of practical problems concerning fluid flow with cavitation are solved.Internal ballistic of impulse water extruder and powder hydrocannon is studied theoretically and experimentally. General theory of hydrocannon for ideal incompressible liquid is developed. Some applied task for different technological processes are solved on the base of electrohydraulic effect.
