Abstract
In the present paper, numerical study of flow and heat transfer properties of RP-3 kerosene in an impingement model are conducted with SST turbulence model and a 10-species surrogate of kerosene. The independence of grids is first studied and the numerical results are compared with experimental data for validation. Characteristics of flow and heat transfer of kerosene flow in the impingement model are studied with different inlet temperatures, dimensionless open areas, and separation distances. The heat transfer coefficients and pressure losses increase with decreasing dimensionless open areas. The separation distance H/d = 2 gets the best heat transfer performance and the separation distance H/d = 3 gets the best heat transfer uniformity on the target plate. Higher inlet temperature gets a higher heat transfer performance and heat transfer uniformity on the target plate.
