Abstract
The present work describes a method which allows the investigation of radiation from simple flow fields produced by vortices and also the calculation of the sound waves excited in a plane, infinite plate which is situated near the flow field. The knowledge of the trajectory and “life-history” of the vortices is necessary for this method. Quantitative calculations have been made for the single two-dimensional vortex filament, for a pair of two-dimensional, spinning vortices, for the collision of two straight lines of parallel vortex filaments with a wall and for the bound vortices which appear on the wings of a propeller together with the hub and tip vortices.
