摘要

A procedure for solving compressible flow within a finite volume, pressure-correction-type scheme, has been devised and successfully implemented in two test cases: a de Laval nozzle and an oxygen jet entering a heated furnace. Both cases have been validated with the analytical solution for the nozzle case and experimental data for the oxygen jet case. The method was successful in predicting the axial variables of the jet, and used to develop a modified turbulence model for such jets.
