• This paper presents a review of the current industry-standard approach to numerical simulation of gas turbine combustion, and an appraisal of likely future developments. The limitations of the current approach are used to indicate where on-going research is being focussed to improve the realism and accuracy of simulations. Significant progress is being made in refined chemistry for hydrocarbon fuels, transported PDF methods for capture of turbulence/chemistry interactions, and soot modelling. For improved representation of turbulent mixing processes, the Large Eddy Simulation approach is showing high potential, whereas for simpler unsteady effects related to acoustic/combustion instability problems, the unsteady RANS approach has demonstrated good predictive potential for only moderate increases in computational cost. As enhanced computing power becomes available yet more sophistication will be built into models and models that are more detailed will be applied to engine representative combustion systems.
