Abstract
The impingement cooling of hydrocarbon fuels represented by kerosene has broad application prospects in the field of hypersonic aircraft and engine thermal protection. However, compared with air and water, the thermal properties of kerosene are more complex and need to be further studied. Using the Reynolds average method and the SST k-ω turbulence model, the superalloy is used as the heat transfer material. By simplifying the model, the effects of different jet structures on the impingement cooling effect under the same inlet conditions are numerically simulated. The wall temperature distribution is used as the evaluation index of heat transfer performance, and the overall design of the stabilizer is based on this. The research shows that the wall temperature of the stabilizer shows a tendency of increasing annularly around the stagnation point. The increase of opening ratio, hole pitch and jet distance will lead to the decrease of heat transfer effect.
