"This work deals with the numerical solution of transonic turbulent flows in external and internal aerodynamics. Turbulent flows are modelled by the system of Favre averaged Navier-Stokes equations. This system is closed by either Kok's TNT k-omega two equation model or explicit algebraic Reynolds stress model (EARSM) of Wallin and Johansson, which is based on TNT k-omega transport equations. Numerical solution is obtained by finite volume method based on HLLC Riemann solver with piecewise linear WENO reconstruction and explicit multistage TVD Runge-Kutta method. Suitable treatment of stiffness due to source terms is also discussed. Numerical method is then tested on some realistic flow problems such as the flow around the RAE 2822 airfoil or flow in SE 1050 turbine cascade."@en . "Praha" .
