Large Eddy Simulation Analysis of Lobed Mixer Nozzle

Large Eddy Simulation (LES) was applied to predict the mixing characteristics of a lobed mixer nozzle analysis. LES was first validated by using experimental data of a convergent-divergent nozzle (CD nozzle) flow. Then, the LES results of the lobed mixer nozzle with a ejector duct were evaluated by comparing with measured data. LES analysis provided more reasonable agreement than Reynolds-averaged Navier Stokes (RANS) analysis.
