It is a challenging task to investigate the regenerative cooling of the variable thrust LOX/LCH4 expander cycle rocket engine. The decreasing methane mass flow rate leads to the two-phase instability in the regenerative cooling channels (RCC) for low engine thrust. In this study, the geometric dimen...
