Study Of The Impact Of Forebody Fluidfield On The Performance Of Sidewall Inlet

Integrated design methodology of Forebody/Inlet is a very important step of integration methodology. In this work, the Forebody/Sidewall Compressiom Inlet integration is researched primally based on theoretical analysis and numerical simulation.With reference to both domestic and foreign literature, this paper writes C language program in the purpose of construct different forebody models with the technology of variable-wedge-angle parametric studying and streamtracing; Referring to the design method of sidewall compression inlet with uniform inflow, it exploringly designs Forebody/Sidewall Compressiom Inlet integration computation models. This paper takes advantage of FLUENT software to numerically simulate the forebody models, analyzes its'main performances, and has confirmed the feasibility of sidewall inlet integration design with the waverider and the high l/d lifting body. The results indicate that by means of altering the axial position of inlet on forebody and the distance between the forebody-shock and the cowl, or changing the head of forebody in parametric method, the mass flow ratio and total pressure recovery of the integration model could be enhanced.
