Numerical Solution of Transitional Flows Using EARSM With Algebraic Model of Transition
J. Holman
Abstract:
The contribution deals with the numerical simulation of laminar-turbulent transition using algebraic model based on computation of the intermittency coe?cient. Algebraic model of transition is implemented to the in-house software for simulation of 2D compressible turbulent ?ows using the Reynolds averaged Navier-Stokes equations (RANS) closed by the explicit algebraic Reynolds stress model (EARSM). The numerical solution is obtained by the ?nite volume method based on the HLLC scheme and explicit TVD Runge-Kutta method. The proposed method is validated on the ERCOFTAC T3 test cases.
Keywords:
