b'Engineer Innovation | Power & EnergyThis is where CFD is really useful - you can try running an actual gas turbine on a different fuel but evaluating the downstream impacts on the entire gas turbine system is very difficult, he saidGreater insight leads to increased innovationOur study shows that LES has a good potential to capture complex flow/flame/acoustic interactions in real gas turbine geometries, explains Dr Moll. This has two strong benefits. First, detailed information regarding flame stabilization and its impact on the thermo-acoustics may be provided, which is of great assistance for gas turbine developersHaving successfully demonstrated the ability of Simcenter STAR-CCM+ in predicting thermo-acoustic oscillations, Dr Moll is confident that this type of simulation can eventually be routinely deployed in the design of future generations of gas turbine:Greater insight leads to increased innovation. CFD will allow us to simulate new burner geometries or new combustion chambers that might offer improved performance, he concludes. The risk is always that if you introduce a new burner or a new combustion chamber, that you might introduce different combustion dynamics. CFD is a -75.-50.- useful pre-screening method for new Figure 4: LES simulations of pure methane combustion technology and a useful explaining method: so, if something does introduce new combustion dynamics, we can explain why, and then makeGreater insight leads toappropriate design changes in response.increased innovation.
