Abstract:
A gaseous wave pressure regulation method comprising(a) a process generating a gaseous wave system through a flow controllable means within a pressure regulation process, wherein said process of generation of gaseous wave interaction is produced by the interaction between a high speed jet driven by a pressure drop of a pressurized gas stream being regulated through a controllable convergent or convergent-divergent flowing passage during pressure regulation processes and a gaseous column in a resonant tube, wherein said gas column is driven in oscillating by a shock wave disk in said high speed jet and pressure-waves feedback from said oscillating gas column, coupled with the oscillation of said shock wave disk in said high speed jet generated by said pressurized gas stream being regulated, and generates an intensive energy-dissipation process by said gaseous waves interaction within said resonant tube and an intensive heating effect on the surface of said resonant tube sustained by said high speed jet generated from said pressurized gas stream being regulated, and(b) a process recovering the energy from said pressurized gas stream being regulated after being depressurized by passing through said surface of said resonant tube containing said oscillating gas column in the form of heat, wherein said pressurized gas stream being regulated is regulated after passing through said flow controllable convergent or convergent-divergent flowing passage and an oscillating chamber to dissipate the energy of said pressurized gas stream being regulated, release the pressure drop energy while being regulated, then recover said released energy from said surface of said resonant tube in the form of heat to compensate for its temperature drop during regulation.
