Fluid Dynamics Simulation : The Next Generation


Large Eddy Simulation enables a high-quality prediction of turbulent flows for digital design
Turbulent flows are hardly solved by a universal numerical method in a practical accuracy and cost,since they are highly non-l i near and unst eady phenomena.
This project develops a standard simulation method for unsteady turbulent phenomena based on Large Eddy Simulation(LES) which is a hope fulapproach to decouple different scales in turbulence.
LES with a hundred million grids enable to simulate unsteady turbulent phenomena accurately enough for the a dvanced digitalde sign of fluid engineering.
LES is a lsofeasible to predict complex problems with turbulence;combust i on and multiphase flows in the energy equipments, flow noise and flow induced vibration in vehicle,

LES of unsteady flow problems.
