Abstract
Frequency modulator consists of a vortex chamber with circular cross-section and a tangential inlet branch. This generates a vortex motion in the flowing medium. The outlet from this is on the top and forms a compression chamber of smaller dia. Arranged around this are a series of smaller outlet chambers with tangential entry from the compression chamber. Fluid then forms a series of small vortices in these chambers. Outlet chambers are arranged around the top of the large inlet vortex chamber. Used to produce sonic and ultra-sonic beams which can then be used to analyse aerosol suspensions. Allows control of the frequency merely by absorbing the flow without any significant change in the resistance to flow.
