International Journal of Aerospace Engineering, Volume 2018, Issue 1, 2018., 2018 The development of high‐performance aeroengine combustion chambers strongly depends on the accuracy and reliability of efficient numerical models. In the present work, a reacting solver with a steady laminar flamelet model and spray model has been developed in OpenFOAM and the solver details are presented.

Numerical Analysis of Turbulent Combustion in a Model Swirl Gas Turbine Combustor
Journal of Combustion, Volume 2016, Issue 1, 2016., 2016 Turbulent reacting flows in a generic swirl gas turbine combustor are investigated numerically. Turbulence is modelled by a URANS formulation in combination with the SST turbulence model, as the basic modelling approach. For comparison, URANS is applied also in combination with the RSM turbulence model to one of the investigated cases.
