5 Best Practices for Gas Turbine Combustion Meshing Using Ansys Fluent

Combustors are complex geometries that have detailed features including fuel atomizers, swirlers, effusion and dilution orifices. Because of the complex nature of the combustor, the meshing process can result in long turnaround times and high costs. Ansys Fluent accelerates the meshing of large, complex geometries, like those of combustors, giving users complete control to generate a high-quality mesh that will yield robust, accurate results. 

This paper discusses the five best practices for meshing gas turbine combustion processes using Ansys Fluent’s patent pending mosaic meshing, which produces a hexahedral dominant mesh in the core and mosaic polyhedral cells that extend to the inflation layers of the wall. These best practices involve:

1. Watertight Geometry Workflow

2. Mosaic Poly-Hexcore Meshing with Parallel Scalability

3. Inflation Layers

4. Mesh Resolution Per Part

5. Target quality metrics
