A Fundamental Study of Leak Detection Technology Using High Pressure Liquid

Abstract

Theoretical study of a liquid leak and gaseous leak under high pressure was conducted in this paper. It is shown that the droplet fall occurs by the large leak of the liquid, and the liquid leak testing can be performed from 1.0×10^-9 Pam³/sec to 1.0 Pam³/sec at the high pressure of 100 MPa. And it is found that the leak flow rate of the liquid increases in proportion to the pressure and that of the gas increases square by the pressure. This analysis gives an index for the determination of the leak judgment value of this liquid leak testing.
