The aim of this paper is to compare various mathematical models simulating the turbulent flow in a solid propellant rocket engine. For comparison, the most frequently used models were chosen for simulations of flow in the S5 rocket engine. For this type of engine experimental data are available allowing comparison of the simulations with reality. The LES Smagorinsky model provided the best results, while type RANS models appeared to be less suitable for this task.
