Abstract
Large Eddy Simulations using an eddy-viscosity and a scale similarity subgrid-scale model are performed in comparison with Direct Numerical Simulations in order to assess the models' capabilities with respect to relaminarization effects. The considered case of mixed convection in a vertical channel is adopted from Kasagi & Nishimura and shows distinct features in the flow close to the heated and cooled channel walls caused by buoyancy. An analysis of the development of coherent structures is performed in order to discern the models with regard to relaminarization effects occuring on the heated channel wall as observed in DNS.
