Large-Eddy Simulation of Supersonic Cavity Flowfields Including Flow Control

A High-Order Compact Finite-Difference Scheme for Large-Eddy Simulation of Active Flow Control

“…[39,40] The procedure employed for parallelization has been demonstrated to be portable, due to the use of the standardized MPI library. FDL3DI has been utilized successfully on a number of different computing platforms, and has maintained a parallel efficiency of 90% for up to 320 processors.…”

“…A summary of these may be found in Ref. [40]. For the simulations presented here, we consider a deep cavity where the length to depth ratio is less than 9.…”

Numerical simulation of supersonic cavity noise

“…Y [3] tested the rationality of the application of he KSKL-SAS and the SST-SAS model in the aerodynamic noise. Donald P. Rizzetta [4] performed the supersonic cavity using a high-order large-eddy simulation. Moreover, a active flow control could be applied by pulsed mass injection to suppress noise.…”

Accurate Flow Prediction for Store Separation from Internal Bay

“…A similar study was carried out experimentally by Zhuang, et.al [4] and a numerical investigation of approximately similar geometry using LES turbulence model was carried out by Rizzetta, et.al [5].…”

“…The grid is shown for every other point in Figure 1. The freestream flow conditions are Mach=2.0, P 0 =2.17x10 5 Pa, and T 0 =336 K, Re/cm=2.33x10 5 . The unsteady cavity solutions were obtained with symmetric and full configurations with and without control to investigate the asymmetric effect of the turbulence model.…”
