Description
  • This work deals with the numerical solution of transonic turbulent flows in external and internal aerodynamics. The mathematical model is based on Favre averaged Navier-Stokes equations and modified two-equation TNT k-omega model of turbulence. This system is discretized by the finite volume method. The HLLC Riemann solver numerical flux with the piecewise linear reconstruction is used for spatial discretization of inviscid flux. Viscous fluxes are approximated by central differencing. Semi-discrete finite volume method is then solved by the explicit multistage Runge-Kutta method. Stability issues of explicit method are also discussed. The numerical method is validated by comparison to theoretical results for the flow around the flat plate. Finally, the method is used for the solution of the flow around the RAE2822 airfoil and the flow in SE1050 turbine cascade.

  • Tato práce se zabývá numerickým řešením turbulentního transsonického proudění ve vnější a vnitřní aerodynamice. Matematický model je založen na Navierových-Stokesových rovnicích s Favreovým středováním a modifikovaném TNT k-omega modelu turbulence. Tento systém je diskretizován metodou konečných objemů, kdy je tok nahrazen numerickým tokem HLLC a při diskretizaci konvektivních členů je využita po částech lineární rekonstrukce. Vazké toky jsou diskretizovány centrálně. Semi-diskrétní tvar rovnic je poté řešen numericky pomocí explicitní Rungeovy-Kuttovy metody. Jsou zde diskutovány problémy stability explicitní metody. Numerické výsledky jsou porovnány jak s teoretickými výsledky pro případ obtékání desky, tak s experimentálními daty pro případ obtékání profilu RAE2822 a protékání turbínovou mříží SE1050. (cs)
