We took advantage of CONVERGE’s autonomous meshing and accurate combustion modeling to simulate an aviation gas turbine, which is included in CONVERGE Studio as an example case. This single-sector combustor case represents a high-power condition and includes wall effusion cooling holes. We used the Flamelet Generated Manifold (FGM) model to simulate the combustion of Jet-A fuel and Adaptive Mesh Refinement to capture the flow through the effusion cooling holes. The video shows the streamlines in the casing and the combustor, as well as wall temperatures and an isosurface of OH representing the flame front. CONVERGE Studio is included with a CONVERGE license at no extra cost, and it contains the setup files for this—and many other—gas turbine example cases. These example cases allow you to conduct parametric studies to determine the sensitivity of spray, combustion, heat transfer, and turbulence models on results such as NOx, flame shape, and wall and exit profile temperatures.
Convergent Science's CONVERGE is an innovative computational fluid dynamics (CFD) software package that eliminates the grid generation bottleneck from the simulation process through autonomous meshing.
