dc.description.abstractIn the present manuscript, we report on the numerical simulation of coaxial nitrogen injection under subcritical and supercritical conditions, where the inner stream is recessed concerning the coaxial one. An incompressible but variable density description of supercritical phenomena is pursued as an alternative to more established compressible formulations, in which we extend past analysis focusing on the evaluation of density to the temperature field validation, according to the available experimental data. The results indicate that recirculation regions are formed as expected at either the inner jet axis or at the post tip between both streams. Furthermore, it is found that the transition threshold between the blockage effect depends on the momentum ratio and differs between subcritical and supercritical conditions.pt_PT
