A system for drying and/or transporting particulate material, including fluidizing the material by means of pulsed air flow in jets which oscillate parallel to the path of motion of a bed of the material in an assymetric sweeping fashion which applies a net transporting force in one sense or direction, or by applying such pulsed flow so that the net force in either sense is zero, to cause drying without transport. The system utilizes phase locked acoustic oscillators to provide sweeping jets of fluid moving in opposite directions for drying and in the same direction for transporting the particulate material. The fluid oscillators are fabricated from 2 groups of molded or extruded members with the members of each group being identical. Spacers are employed to position the parts whereby to provide the desired oscillator configuration.
In combination for treating a bed of particulate material, a support for said bed of particulate material, said support being pervious to jets of gas, an array of jet sources underlying said support and directing jets of said gas against said bed, said array comprising plural oscillators, means applying said gas under pressure to all said plural oscillators, each of said oscillators including an interaction region, a discharge nozzle, a power nozzle for issuing a stream of fluid through said interaction region toward said discharge nozzle and at least one resonant chamber located along one side of said interaction region between said nozzles, and phasing means intercoupling said resonant chambers to produce phase coordinated sonic oscillations in said chambers.
In combination in a system an array of at least two oscillators, each of said oscillators including an interaction region, at least one separate resonant chamber in sonic communication with said interaction region, a discharge passage, means for issuing fluid across said interaction region toward said discharge passage, and passages intercoupling said resonant chambers to enforce phase coordinated oscillations in all said oscillators.
A plurality of non-moving part phase coordinated oscillators comprising a plurality of oscillators each including means for receiving a stream of fluid, an interaction region, a passage for issuing a stream of fluid across said interaction region towards said means for receiving and resonant chamber means in fluid communication with said interaction region, and phasing means providing fluid coupling between said resonant chamber means of different oscillators to produce phase coordinated oscillations in said oscillators.
Plural oscillators comprising a first plurality of members each having a bottom wall of finite length, a pair of side walls extending upwardly from and generally transverse to said bottom wall and a pair of concave surfaces extending each from a different one of side walls, a second plurality of members each having a top wall, a pair of diverging side walls each extending from a different end of said top surface generally transverse thereto and a pair of concave surfaces each extending from a different one of said side walls, said members of said first plurality of members being arranged with said bottom walls co-planar and said side walls parallel to a common axis parallel to said bottom walls, and said members of said second plurality of members being arranged with said top walls coplanar and said sidewalls spaced equidistant from one another and aligned along an axis parallel to said top and side walls thereof, and means for positioning said members relative to one another such as to define between adjacent sidewalls of each pair of said first members a power nozzle, between adjacent sidewalls of each pair of said second members an output passage in fluid receiving relationship with said power nozzle and between each pair of a first and second member a resonant cavity communicating with a region between said power nozzle and said output passage.
