| Description
| - Tato práce se zabývá numerickým řešením transsonického proudění v turbínových mřížích, které je založeno na modelech 2D nevazkého a vazkého jedno- a dvou-fázového proudění, tj. na Eulerových a Reynoldsových průměrovaných rovnicích. Tyto rovnice jsou v případě dvou-fázového proudění svázány s transportními rovnicemi pro parametry Hillovy aproximace, která je použita pro popis spektra kapek. Dvě metody konečných objemů jsou použity pro výpočty jedno-fázového proudění. První je založena na Laxově-Wendroffově schématu a konečných objemech typu cell-vertex. Druhá je založena na Roeho schématu s vhodnou rekonstrukcí. Numerická metoda pro dvou-fázové proudění je založena na metodě rozkladu operátoru. (cs)
- This work deals with a numerical solution of a transonic flow through turbine cascades based on models for 2D inviscid and viscous single- (air) and two-phase (wet steam) flow - Euler and Reynolds averaged Navier-Stokes equations. These equations are in the case of two-phase flow connected with conservation equations for parameters of Hill's approximation, which is used for the description of droplets spectra. A two finite volume methods are used for the computation of single-phase flow. The first one is based on a Lax-Wendroff type cell-vertex scheme with a conservative artifical viscosity terms. The second one is an finite volume upwind method based on approximate Riemann solver, a proper reconstruction and a limiter. Numerical method for two-phase flow is based on fractional-step method due to the different time scales of convection-diffusion and of condensation mechanism.
