چکیده

In the present study, a hydrogen and oxygen heat-sink engine thrust chamber corresponding injection faceplate with discrete slot orifices are devised to study cooling performance near region. Moreover, set of experiments numerical simulations conducted evaluate effects various factors on combustion film efficiency. According obtained result, circumferential efficiency has an M-shaped distribution in near-injector Furthermore, it been discovered that when flow ratio increases, so does This is especially more pronounced range 30–80 mm from faceplate. The found be proportional rate ratio’s 0.4 power. Compared thickness, reduction width beneficial improving efficiency, advantage prominent for small ratios. addition, amount coolant not enough, effect orifice better than common cylindrical orifice. article demonstrates setting area adjacent effective way reduce uneven wall surface temperature.
