Detached Eddy Simulations of Supersonic Flow over Cavity
نویسندگان
چکیده
Detached Eddy Simulations are performed for unsteady three-dimensional supersonic turbulent flow over an open L/D = 5 cavity at free-stream Mach number of 1.19. Numerical results are obtained from the explicit solution and Shear-Stress-Transport based simulations using the 3 order Roe scheme. Computational results are presented for the unsteady vortex and shock structures. The acoustic response of the cavity is presented in the form of pressure fluctuations and sound pressure level spectra. The computational results are compared to existing experimental data and to results obtained from twodimensional Reynolds Averaged Navier Stokes with algebraic turbulence model.

Evaluation of Detached Eddy Simulation for Turbulent Wake Applications
Simulations of a low-speed square cylinder wake and a supersonic axisymmetric base wake are performed using the Detached Eddy Simulation (DES) model. A reduced-dissipation form of the Symmetric TVD scheme is employed to mitigate the effects of dissipative error in regions of smooth flow. The reduceddissipation scheme is demonstrated on a 2D square cylinder wake problem, showing a marked improve...

A numerical study is conducted to investigate steady and pulsed fluidic actuation in transonic flow over an open cavity. Numerical results are obtained for the unsteady threedimensional flow with three different steady mass injection rates and one pulsed injection upstream of the cavity. The simulations are carried out using the full 3-D Navier Stokes equations with the two-equation k-ε based D...
