5 Best Practices for Hydrogen Gas Turbine Combustor Meshing Using Ansys Fluent 

The International Air Transport Association (IATA) set a target to reduce CO2 emissions by 50% in 2050 (compared to 2005 emission levels), with no increase in net emissions after 2020. They also expect the global aviation demand to double to 8.2 billion passengers per year by 2037. These issues have prompted the aviation industry to focus on transitioning from natural gas to sustainable aviation fuels (SAF), hydrogen, and hydrogen blends.

Last year, we published our 5 Best Practices for Gas Turbine Combustion Meshing Using Ansys Fluent, but hydrogen-fueled combustors pose their own unique challenges and require different best practices. This paper will cover our five best practices for hydrogen gas turbine combustor meshing using Ansys Fluent, which include:

  1. Watertight Geometry Workflow
  2. Mosaic Poly-hexcore Meshing with Parallel Scalability
  3. Inflation Layers
  4. Mesh Resolution Per Part
  5. Target Quality Metrics
