Gas generator and cavitator for gas generation

A gas generator for gasification of liquids, e.g. vapour from water, said gas generator comprising a main rotor body being rotatably mounted to a static support framework such that the main rotor body is arranged to rotate around a rotor body centre axle, said main rotor body comprising one or several main rotor body channels, provided with a rotor body channel inlet and a rotor body channel outlet, for guiding a flow of a liquid from said rotor body channel inlet being located at a distance R1 in the radial direction from the rotor body centre axle towards said rotor body channel outlet being located at a distance R2 in the radial direction from the rotor body centre axle wherein R2>R1 such that a liquid in the rotor body channel is forced from the rotor body channel inlet towards the rotor body channel outlet by centrifugal forces as the main rotor body rotates around the rotor body centre axle, said main rotor body further comprising one or several cavitators each one comprising one or several cavitator channels provided with a cavitator channel inlet (301) being located closer to R2 than R1 and a cavitator channel outlet, said cavitator channel inlet being connected to the rotor body channel outlet for guiding said liquid flow to the cavitator for cavitation of the liquid, said one or several cavitator channels is designed with cavitation inducing means, e.g. flow guiding or restricting means, wave shaped channel walls (314 a-c), protrusions and widenings, surface irregularities such as cavitation generating indentations or a combination thereof, in order to induce a differentiated pressure within the liquid in the cavitator from the inertia of the liquid and the centrifugal forces induced by the rotation of the main rotor body thereby causing cavitation in the liquid flowing through the cavitator channels and the cavitation inducing means.
