Coherent-vorticity Preserving (CvP) Dynamic Modeling of High-Reynolds-Number Vortex Dominated Flows https://s.uconn.edu/meseminar3/12 Abstract: This talk will discuss a novel dynamic subgrid-scale (SGS) modeling approached called Coherent-vorticity Preserving (CvP) Eddy-Viscosity Correction [1], which has been designed for very rapid evaluation of the SGS vortical activity, enabling local and instantaneous modulation of the turbulent eddy viscosity. The CvP-LES approach has been validated against large-scale direct-numerical simulation (DNS) employing […] Categories: Upcoming Seminars |

LES of lean-burn combustors: modelling perspectives and prediction of unsteady phenomena https://s.uconn.edu/meseminar3/5 Abstract: Energy demand and the need to reduce emissions have pushed combustion research towards the development of more efficient, environmentally-friendly engines. In lean-burn systems both high efficiency and low emissions can be achieved in principle by controlling the flame temperature; however the short resident times in practical systems and the unsteady coupling between turbulent […] Categories: Upcoming Seminars |
