RISLarge Eddy Simulation Exploration of Passive Flow Control Around an Ahmed Body
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large eddy simulations (LES) are used to study passive flow control for drag reduction in a simplified ground vehicle. Addon devices in the form of short cylinders are used for the formation of streaks in the streamwise ...
Very Large Eddy Simulation of Passive Drag Control for a D Shaped Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The numerical study reported here deals with the passive flow control around a twodimensional Dshaped bluff body at a Reynolds number of Re=3.6أ—104. A small circular control cylinder located in the near wake behind the ...
Optimization Using Arbitrary Lagrangian–Eulerian Formulation of the Navier–Stokes Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a new shape optimization method by using sensitivities obtained from the Arbitrary Lagrangian–Eulerian (ALE) form of the Navier–Stokes equations. In the ALE description, the nodes of the ...
