摘要

A transparent injector was made to learn the flow field of theinjector. Water is used as the stimulant. For different mass flowrate, it takes several milliseconds for liquid phase to fill theinjector. 80% of the time is used to fill the swirl chamber. Thediameter of gas core is about 1mm. Area-weighted totalpressure and velocity were used to compare the influence ofdifferent sections. Total pressure loss in the convergentsect ion occupies 55% of the total pressure loss.
