The invention discloses a radial-flow type fluidic
pressure wave supercharger, which can realize the
energy exchange between the
high pressure gas and the low pressure gas by running the
pressure wave, avoid loss of mixed and diffused energy and has the advantages of high isentropic efficiency, low rotating speed,
operability with liquid, sufficient exhaust and on the like. For adopting a pressure oscillating tube channel with variable rectangular cross-section, the incidence loss and the flowing loss of the
jet flow are reduced; the channel is a bending flow channel arranged along the radial
radiation, the process of expanding and compressing is strengthened and the sufficient
discharge of the compressed gas is accelerated by using the
centrifugal force; pressure balancing holes are arranged in the
machine, so that the performance is kept balanced at the different pressure ratios; a pressure expanding flow guider is arranged at a compressed gas outlet in order to transform the
dynamic energy of the gas flow effectively. The radial-flow type fluidic
pressure wave supercharger can fully utilize the pressure energy in the production process and the pressure energy in the stratums of
natural gas, thereby providing an efficient device selection for utilizing the pressure energy sources effectively.
