The paper describes the results of a computational study of the strongly swirling isothermal
flow in the combustion chamber of an industrial gas turbine. The flow field characteristics are
computed using large eddy simulation in conjunction with a dynamic version of the
Smagorinsky model for the sub-grid-scale stresses. Grid refinement studies demonstrate that
the results are essentially grid independent. The LES results are compared with an
extensive set of measurements and the agreement with these is overall good. The method is …
