Large-eddy simulation of compressible rectangular duct flow

Numerical Simulation of Turbulent Subsonic Compressible Flow through Rectangular Microchannel

In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...

Large eddy simulation of compressible turbulent jets

Increasing noise regulation at urban airports force jet engine manufactures to develop and build quieter engines. Over the last 10-15 years, a significant reduction in fan and mechanical noise has been achieved. However, the reduction in jet noise over the same time period is fairly small and a major reduction in acoustic emissions of jet engines has to come from a reduction in jet noise. Tradi...

Large Eddy Simulation of a Turbulent Reacting Compressible Jet

We report results of a Large Eddy Simulation (LES) effort of turbulent compressible nonpremixed reactive jets. It is well known that there are several difficulties associated with compressible reactive flows in comparison with incompressible flows. In incompressible flows, the energy and mass conservation (for constant density flows) equations are decoupled from the velocity field. Moreover, th...
