The accurate and efficient simulation of combustion flows remains a significant challenge. Recent advancements in turbulence modeling and numerical algorithms at the Notre Dame Turbomachinery Laboratory (NDTL) have demonstrated promising new capabilities. The temperature contours shown above illustrate the Wavenumber Adaptive Simulation (WAS) method developed at NDTL as well as the solution from a traditional Large Eddy Simulation (LES). The WAS technique is a form of hybrid turbulence model that is both accurate and numerically efficient. Both simulations provided a similar level of resolution and accuracy, while the WAS required approximately half of the computational costs.
