Kurzfassung
We performed Direct Numerical Simulations (DNS) and Large Eddy Simulation (LES) of turbulent mixed convection in the minimal flow unit. DNS of turbulent isothermal channel flow have been conducted to demonstrate the predictive capability of the second order accurate finite volume method we used. For the mixed convection case we obtained that the turbulence intensity increases due to bouyancy. Consequently, we reduced the spanwise width of the domain to show that turbulence can be sustained for mixed convection. Additionally, we launched a LES of mixed convection with the dynamic Smagorinsky model. The obtained LES results agree well with the corresponding DNS data.
