Turbulence Control Simulation using the Variational Multiscale Method
Srinivas Ramakrishnan, S. Scott Collis · APS Division of Fluid Dynamics Meeting Abstracts · 2001
The capabilities of the variational multiscale (VMS) method are explored in the context of turbulence control by applying VMS to the simulation of a simple opposition-control strategy for turbulent channel flow with the results compared to prior direct numerical simulations and large-eddy simulations based on the dynamic subgrid-scale model. In all cases, the VMS method is found to be more efficient and more accurate than the dynamic model, and the simplicity, accuracy, and generality of VMS makes it particularly attractive for turbulence control investigations
