Large eddy simulation of a forward–backward facing step for acoustic source identification
The feasibility of using a commercial CFD code for large eddy simulation (LES) is investigated. A first test on homogeneous turbulence decay allows a fine-tuning of the eddy viscosity with respect to the numerical features of the code. Then, a flow over forward–backward facing step at Reynolds number Reh 1⁄4 1:7 10 is computed. The results found show good agreement with the new LDA data of Lecl...
متن کاملLarge - eddy simulation of a backward facing step ow using a least - squares spectral element methodBy
We report preliminary results obtained from the large eddy simulation of a backward facing step at a Reynolds number of 5100. The numerical platform is based on a high order Legendre spectral element spatial discretization and a least squares time integration scheme. A non-reeective outtow boundary condition is in place to minimize the eeect of downstream innuence. Smagorinsky model with Van Dr...
متن کاملSimulation of Steady, Laminar Flow Over a Backward-Facing Step
A 2D Navier-Stokes solver was developed to simulate steady,laminar flow over a backward-facing step of height h. The step expansion ratio=1/2 and the flow at the step was assumed to be fully developed, laminar channel flow. The Reynolds number for this flow was defined as Re=Uh/ν. The 2D incompressible Navier-Stokes equations was solved in generalized curvilinear coordinates using artificial co...

15 صفحه اولReverse flow regions in three-dimensional backward-facing step flow
Laser-Doppler velocity measurements adjacent to the bounding walls of three-dimensional (3-D) backward-facing step flow are performed for the purpose of mapping the boundaries of the reverse flow regions that develop in this geometry (adjacent to the sidewalls, the flat wall and the stepped wall) as a function of the Reynolds number. The backward-facing step geometry is configured by a step hei...
