Abstract:
Results are presented for the application of an acoustic/viscous splitting technique to die computation of flowfields within two-dimensional rectangular cavities for moderate Reynolds numbers. This technique has been previously applied to cavity flows but results were studied only in die acoustic far field and limited to low Reynolds numbers. Implementation of a large eddy simulation model has allowed the Reynolds number range to be extended and direct comparison of computations with wind tunnel results for the cavity near field demonstrates that this technique, which is two-dimensional, may be used to study three-dimensional cavities, provided such cavities are fairly large in their transverse direction. In addition, the flowfield calculation is shown to be sensitive to such parameters as boundary layer thickness, filter width used in the large eddy simulation implementation, and incoming velocity profile.
