Abstract:
A pressure wave generator with dynamic reflector of pressure impulse is disclosed which comprises an outer fixed and an inner coaxially-rotating cylindrical elements with the given profiled openings of the given shapes and sizes in the solid walls and a dynamic reflector of pressure impulse, configured in the solid wall of the inner rotating cylindrical element having a longitudinal radial-azimuthal variable-concave surface. Such concave surface provides a decomposition of the reflected pressure impulse to a radial and azimuthal component, especially important on the stage of decrease of the pressure amplitude from a maximal value to zero. Variation of the curvature of the radial-azimuthal shape of the concave surface provides a maximal azimuthal component and a minimal radial component of the mechanical reaction of the shaft of the pressure wave generator. The helicoidally-shape of the inner surface of a collector add an azimuthal motion to reflected pressure impulse.
