Popis: A numerical procedure to analyze a flowfield through or around a Langley-typed scramjet engine inlet with a strut and an I-shaped thick cowl is proposed. To treat boundary conditions (wall, symmetry etc.) accurately, all boundaries are mapped onto faces of five rectangular parallelepipeds. The governing equations are the 3D full Navier-Stokes equations. The TVD scheme is applied for spatial discretizations and the IAF method, for time integration. To show capability of the numerical procedure, numerical simulations of flow have been carried out under Mach number 4 of free stream about four inlet models, whose struts differ in lengths but have the same contraction ratios. The result has made no great difference from each other in inlet performance such as mass capture ratio and total pressure recovery ratio.
