摘要

The continuity, momentum and energy equations for two-dimensional compressibleturbulent boundary layers are solved using the k-epsilon turbulence model and the extended mixing length approach to calculate the shear stress terms. The finite difference equations are set up applying Keller's box scheme and the resulting tridiagonal matrix system is solved by the block elimination method. Newton's iteration procedure is used to converge the solution. Results obtained from computations showed only a slight difference between the two methods. Both methods showed satisfactory agreement with experimental data for test cases.
