Wall pressure fluctuations generated by a pair of vortices
Abstract
The wall pressure field generated by two potential vortices of equal circulation situated in the vicinity of a flat wall is calculated. This configuration is regarded as a strongly simplified flow model of the mutual influence between vortices and walls. Two different types of flow fields are distinguished. Either the vortices remain together, or one of them overtakes the other and separates from it increasingly. It is found that although the far field generated by two adjacent vortices is similiar to the velocity field of a single vortex of twice the circulation, the pressure field is quite different.
