Exhaust gas recirculation (EGR) can significantly increase CO₂ concentration in industrial gas turbine exhaust, improving the efficiency of downstream carbon capture. However, higher EGR levels also make combustors more susceptible to unsteady flames and thermoacoustic instabilities.
In this webinar, we present GPU-accelerated large eddy simulations (LES) of Solar Turbines’ Taurus 60 SoLoNOx combustor using Fidelity CFD to show how EGR affects flame dynamics, emissions, and the onset of strong pressure oscillations. Using full-annular simulations, we demonstrate why full-domain, high-fidelity modeling is essential for accurately predicting EGR limits and enabling carbon-capture-ready gas turbine designs
What you’ll learn?
- How increasing EGR changes flame structure, mixing, and unsteadiness in a dry low-NOx industrial gas turbine combustor.
- Why higher CO₂ dilution can trigger combustion instability and pressure oscillations.
- Key differences between sector and full-annular LES
- How circumferential instability modes emerge only in full-domain simulations.
- How simulation results compare with experimental observations
Why attend?
- Gain practical insight into EGR tradeoffs for industrial gas turbines
- See how high-fidelity simulations with Fidelity CFD support carbon-capture-ready designs
- Understand when simplified models are sufficient—and when they are not
- Learn from a real industrial combustor, not an idealized test case
Who should attend?
- Gas turbine and power generation engineers
- Engineers working on emissions reduction or carbon capture
- CFD and combustion practitioners at any experience level
- Technical managers and system engineers involved in gas turbine design
