Abstract
Large-eddy simulation of an atomizing spray issuing from a gas-turbine injector is performed. The fil-
tered Navier­Stokes equations with dynamic subgrid scale model are solved on unstructured grids to com-
pute the swirling turbulent flow through complex passages of the injector. The collocated grid,
incompressible flow algorithm on arbitrary shaped unstructured grids developed by Mahesh et al.
