They developed a simplified model to evaluate the thermal stratification in solid fin as well as the coolant.…”

Thermal analyses supporting the development of a liquid rocket engine

“…For the thrust chamber cooling system, a counter-flow strategy has been chosen: the refrigerant (CH4) enters the inlet fuel manifold (placed on the bottom of Figure 3) in liquid phase (at pressure and temperature, respectively, higher and lower than the critical values); then methane comes in the cooling jacket in the counter-flow direction with respect to the combustion gases. The propellant temperature raises, due to the energy released by combustion gases, and a phase "pseudo-change" occurs; then, methane comes in the fuel dome as a supercritical vapour and finally injected into the chamber through the injectors where mixes liquid oxygen [13]- [15] and burns. The cooling jacket is composed by rectangular-shaped channels, defined in the bottom part by a copper alloy liner, brazed on a close-out of Inconel©.…”
