Modeling of Oscillating Flow Past a Vertical Plate

The unsteady Euler or the Navier-Stokes equations in the case of separated flows due to the oscillating flow past a two-dimensional vertical plate, were solved using a finite volume method. The predicted inertia and drag coefficients were compared with each other and with the measurements from a known experiment, over a range of Keulegan-Carpenter numbers. In the finite volume method, the fluid domain was discretized into quadrilateral cells or volumes. It is found that the force coefficients produced by either the Euler or the Navier-Stokes solver, are close to each other and also to measurements, especially for lower values of the Keulegan-Carpenter number.
