Abstract
Methods and apparatus for controlling the flow of fluid around an object which include means to periodically vary or fluctuate the direction, speed or magnitude of the fluid flow. The fluid flow is particularly controlled to control eddy formation. The fluid is preferably a gas or vapor.
Claims3
An apparatus for controlling the flow of a fluid stream around an object which comprises means to periodically vary the magnitude of velocity of flow of at least a portion of the total fluid stream in such a manner so as to prevent the formation of eddies in said fluid stream in the vicinity of said object, said means to periodically vary the magnitude of velocity comprising means to vent said portion of said fluid stream.
