Passive Control of Flow Separation over a Circular Cylinder with Electro-Magnetic Fields: Numerical Simulation

چکیده
Abstract A new second order theoretical model of the combined interaction of externally applied electric and magnetic fields and viscous incompressible fluid flows has been rewritten as a system of first order partial differential equations. The system was solved using a least-squares finite element model on an unstructured grid. The numerical algorithm is very stable and accurate. The accuracy was confirmed by comparing the numerical results against simple analytical results for a magnetohydrodynamic flow between two parallel isothermal infinite stationary plates. The method was used to investigate the electro-magnetic control of the flow over a circular cylinder at low Reynolds numbers. Results show that with a certain configuration of electrodes and magnets, the combined electric and magnetic fields can be used to remove flow separations in steady flow and eliminate vortex shedding in unsteady flow.

Numerical Simulation Study on a Passive Jet Flow Control Method to Suppress Unsteady Vortex Shedding from a Circular Cylinder
A passive jet flow control method for suppressing unsteady vortex shedding from a circular cylinder via a numerical simulation is presented in this paper. The circular cylinder is wrapped in a hollow pipe. There are a set of the suction/jet holes on the windward side and leeward side of the outer surface of the pipe. The oncoming flow enters into the hollow pipe through the inlet holes and then...
