报告摘要：
In this seminar improved predicting capabilities of the in house developed solver SPARC applying LES for reacting flow fields will be presented. The solver uses a block structured Finite Volume scheme to solve the compressible Navier-Stokes equation with central differencing up to 4th order accuracy. The approximated Riemann solver HLLC has been recently implemented and compared to above mentioned scheme. Classical subgrid scale models like fixed coefficient and dynamic Smagorinsky models and Monotonically Integrated LES (MILES) and a newly proposed High-passed filtered Eddy viscosity model have been used and compared.

It will be shown that accurate predictions of the above mentioned test cases has been calculated provided that the vortical regions are sufficiently resolved ( up to 11 million points) and that accurate and non-reflecting boundary conditions have been used.
