Experimental Research of the Possibility of Applying the Hartmann – Sprenger Effect to Reduce the Pressure of Natural Gas

Abstract

A variant of a quasi-isothermal pressure regulator is proposed, which assumes the mixing of flows after energy separation. According to the results of experimental studies using three resonators in regurgitant mode, the medium resonator demonstrated the highest reliability of functioning in non-stationary conditions. In general, the greatest reliability is achieved in the first half of the range of distances between the nozzle and the resonator.
