LES of spray in compressible flows on unstructured grids

In this paper we report some results of our numerical simulations of sprays in compressible flows using Large Eddy Simulation. The combined LES- and spray code has been applied to the computation of the flow and spray injection into a swirl generator of a gas-turbine. The interaction between the spray jet and the flow field has been investigated. A dynamic SGS model has been used and results have been compared with the experimental data.
