AbstractCharacteristics of flow and heat transfer of kerosene impingement jets were studied numerically. The coupled effect of heat transfer of fluid and structure was investigated. Numerical simulation of fluid flow shows that compared to convective heat transfer of kerosene flow in cooling channels, impingement jet cooling significantly enhances heat transfer ability. At the same time, the pressure loss is below one atmospheric pressure. Both stress and strain of high temperature nickle-based alloy structure were analyzed with typical thermal loading and impingement cooling effect. The numerical results show that temperature distribution in the hot surface of the solid structure is relatively uniform and far below the maximum allowable temperature of the alloy material. The strength analysis shows that both stress and strain of the solid structure meet the material requirements.
