Zh. Vychisl. Mat. Mat. Fiz. 45, No. 10, 1870-1885 (2005); translation in Comput. Math. Math. Phys. 45, No. 10, 1802-1814 (2005).
The authors investigate spatial stationary gas flows in nozzle systems of ejector type. A strong interaction of the interior gas flow with the nozzle streamline gas flow plays a remarkable role in such systems. The authors propose a mathematical model of the gas flow based on averaged Navier-Stokes equations in two-component equilibrium turbulent medium.
