Abstract

A computational study of the combustion process inside micro- turbine engines is presented. Different turbulence models are assessed and results are compared against experimental data. Results indicate that rans models and les with dynamic Smagorinsky sub-grid model fail to achieve convergence or accurate solutions at the meshes em- ployed in this study. Less accurate results are obtained for the des when compared with les-wale. In terms of the combustion, the out- let flow presents temperature gradients that are likely to affect the turbine performance.
