Аннотация

An adaptive Finite Element Method (FEM) is used for the solution of turbulent reactive flows in 3D utilizing massively parallel methods for fluid dynamic and combustion modeling associated with engines. A dynamic LES method permits transition from laminar to turbulent flow - no assumptions are required concerning turbulent sublayers near walls in bounded flows. This capability is ideal for engine configurations where the turbulent wall layers are never in equilibrium and the flow is not always turbulent. The developed h-adaptive FEM flow solver uses 'h' adaptation to provide for grid refinement. The FEM solver has been optimized for parallel processing (using MPI) for cluster and high performance computers and can solve multi-species fluid problems using a dynamic Large Eddy Simulation (LES) model for turbulent reactive flow.
