In this study numerical modeling ideal gas transient flow in nozzle with inlet temperature 300k that based on 2D numerical flow by use of computational fluid dynamics was investigated. Grid example simulated by second order. CFD simulations are carried in turbulent flow. In turbulent flow used inviscid model. From figures observed fluid transient flow in distance 0.05 from initial nozzle. Conclusions CFD simulation compared with experimental equations in references and results of experimental are in good agreement with the software measured speeds, particularly the location of the velocity fluctuations. Simulations of Mach number in transient flow are more than velocity in sources, why wall in nozzle.
