【 摘 要 】

Turbulent flushing flow of methane in Laval nozzles are investigated. To describe the motion of vapor-liquid mixture are used Favre averaged over the set of equations including the equations conservation of mass, momentum, and energy for a homogeneous mixture consisting from liquid and vapour phases. Numerical flow simulation based on cavitation approach using an additional transport equation for the volume fraction of the liquid phase. The study of the expiry of boiling methane at different degrees of underheating and the back pressures in the Laval nozzle are performed.
