Abstract In this paper, shock train behavior in two-dimensional convergent-divergent nozzle (CDN) has been investigated numerically using various turbulence models including k-. renormalized group (k-w. RNG), shear stress transport k-. model (K-w. SST), Spalart-Allmaras (S-A) and Reynolds stress model (RSM). The results are compared with experimental data and analytical relations. The results show that the data obtained by k-. SST and S-A models are appropriate to the cornet case. The results of RSM better than the K-. RNG model, so that squared correlation coefficient (R2) for RSM is an average 15.5% more than k-. RNG model. Suitable agreement between the experimental and numerical results validates the numerical method and confirms its ability to model the similar cases.
