Gas Turbine Combustion CFD Simulation: AVL Fire, Siemens Star-ccm+, Ansys Fluent and Converge
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Gas turbine combustion can be a challenge to achieve accurate and reliable CFD simulation results. Computational efficiency requires appropriate mesh resolution and turbulence, spray, combustion, and emissions models that provide an appropriate level of detail. With using advanced and specilized CFD tools such as AVL Fire, Siemens Star-ccm+, Ansys Fluent and Converge, Enteknograte engineers can accurately predict important kinetically limited gas turbine phenomena such as ignition, flashback, and lean blow off. In addition, we can investigate the combined effects of chemistry and turbulence and optimize combustor performance parameters.
Enteknograte Simulation service for gas turbine combustion include:
- Modeling of ignition and flame propagation with representation of the spark energy, volume, duration, and flame kernel formation and propagation
- Spark modeling, combined with detailed chemistry
- Effect of fuel/air ratio and burner spacing on relight propagation time
- Simulating Lean blow off (LBO) including both gaseous and liquid fuels and maximize combustor performance factor for lean premixed systems to reducing flame temperatures and thus inhibiting NOx formation
- Simulation Flashback ( flame speed of the fuel can overcome the flow velocity and flashback occurs and flashback occurs) of premixed fuel/air systems to investigate probability of damage to equipment.
- Spray modeling of liquid fuel simulations of gas turbines including all steps of the spray process, including primary and secondary breakup, filming, splashing, coalescence, and collision.
- Simulation of emissions of pollutants such as NOx, CO, and soot as a design parameters for gas turbines
- Coupled combustion – CHT (conjugate heat transfer) simulation to predict combustor wall temperatures which captures flame shapes, cooling flows, and metal thermal conditions
