Oscillatory gas flow generator using isothermal chamber

DOI

Description

There is no effective method to calibrate the dynamic characteristics of gaseous flow meters. This is because the density of these fluids changes largely with respect to the variation in both pressure and temperature. In this paper, the development of an oscillatory gas flow generator using isothermal chamber is presented. This generator can generate the oscillatory mass flow including reverse flows. The generator consists of an isothermal chamber, two spool type servo valves and an ejector. It is noted that the oscillatory gas flow generator can generate the oscillatory flow for more than 10 minutes. The effectiveness of the generator is demonstrated
