Phenomenology of Oxygen Flow Parameters Inside Cooling Jacket of Liquid-Propellant Engine Chamber

A calculation method of process characteristics of liquid oxygen flow which is before, trance- and supercritical states inside cooling jacket of liquid-propellant engine chamber by motive power about 50 kN was developed. It takes into account the flow multidimensionality in a cooling circuit, heating of a cooler and hydraulic losses. At the set operating regimes for the liquid-propellant engine chamber the temperature values of a cooler, a speed field are obtained. Moreover, the calculation results of the stress and deformed state are given within boundary sections of a cooling circuit and in the bringing collectors of the liquid-propellant engine chamber. Optimizations recommendations of a hydraulic circuit are formulated for efficiency increase of cooling of the liquid-propellant engine chamber and decrease in hydraulic losses.
