Mathematical modelling of a compressible oxygen jet entering a hot environment using a pressure-based finite volume code

► We devise a procedure for solving compressible flow within a finite volume code. ► The code has been used to model the case of an oxygen jet entering a heated furnace. ► The code has been validated using experimental data for the oxygen jet case. ► A modified turbulence model has been developed for compressible jets. 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.
