Abstract: The two phase probe able to measure the liquid mass flux and gas/liquid mixture ratio distribution at the same time was studied by experimental researches on the two phase flow field of the coaxial injector of a liquid rocket engine. The experimental calibration and theoretical amendment of this probe were also studied. The design of this probe has been proved successful by measurement of the mass flux and mixture ratio distribution.

Key words: injector, probe, two phase flow
