The Theoretical Analysis and Experiments of Using Ultrasonic to Inspect the Leak Amount

The function relationship between acoustic intensity of eyelet leak noise frequency section and Re was discussed.Through the function,it can get the Re after measuring the acoustic intensity within a certain frequency band,and then get the mass flow rate of the leak.The experimental result expresses(that) values of it tally with theoretical deduction result,and this is practical in measuring the leaking mass(flow) rate of gas systems with pressure.
