Abstract

Implicit Large Eddy Simulation (ILES) in conjunction with high resolution and high order computational modelling was applied to a turbulent mixing jet of a fuel injector in gas turbine combustors. In the ILES calculation, the governing equations for three dimensional, single phase, nonreactive multi-species compressible flow were solved using a finite volume Godunov method. A fifth-order accurate methods was used to achieve high order spatial accuracy and a second order explicit scheme was applied for time integration. Comparison of mean and fluctuating velocity components and mixture fraction with experiment and conventional LES demonstrated that the ILES successfully captured the turbulent flow structures without explicit subgrid scale modelling.
