Abstract:

Large eddy simulations LES are performed for two representative complex geometry problems of particular interest to turbomachinery flows, First problem studied is the flow field inside a trapped-vortex combustor. Second problem is the unsteady interaction of rotor blade with stator blade wake field. The representation of complex geometry is done using immersed boundary method IBM. Two different implementations are presented for the body force terms.
