The disintegration phenomena of a liquid jet issued from a co-axial injector of liquid rocket engine with recess was investigated experimentally using a transparent injector model with a rectangular cross section. In contrast to a previous research, the present injector has a gas flow channel at only one-side of liquid injection post, which prevents the liquid injection post from mechanical vibration. It was found that the atomization mechanism relates closely to a gas pressure in a recess. Critical Reynolds and Weber numbers were almost the same as those obtained by using a rectangular injector with a gas flow channel in both sides, that was used in a previous research.
