Understanding physical behaviors in harshenvironments is extremely hard, and at times,critically important. That is the situation GeneralElectric (GE) engineers faced when designing theirnew heavy-duty gas turbine generator. Gaining
even 1% greater efficiency could save their electric utility customers millions of dollars andimprove GE’s world-wide competitiveness. Thekey issues involved a better understanding of the fluid dynamics and reactive flow behaviors in the turbine’s 1,500 degree Celsius combustion chambers and the interactions between the 2 to 16 individual flames in the chambers. GE Power engineers had reached the limits of theory and experiments, motivating them to apply advanced modeling and simulation.
