Based on the theory of boundary layer theory and vortex theory of fluid mechanics, a self-suction self-excited oscillation pulsed jet aerator is introduced in this paper. This new type of jet aerator adopts self-excited oscillation cavity to replace the traditional mixing tube. Air and oxygen-demanded water are forced to intermix, compound and oxygenize violently in the cavity under the effect of self-excited oscillation, then eject through the specially shaped tail tube in the pulsed mode. Theoretical analysis and preliminary industrial experiments show that the new type of jet aerator has an excellent performance of intermixing, compounding and aerating, and that the oxygen-demanded water ejected through the specially shaped tail tube has an intensive pulsation effect.
