<p>A system for conveying fluid through a conduit that creates a strong laminar flow of the material surrounded by a boundary layer flow of the same or a different flowable material, such that long transport distances through dramatic elevation and directional changes can be achieved. Some embodiments of the system include a blower assembly, an inlet conduit, an outlet conduit and a mixing chamber, wherein the mixing chamber includes an outer barrel, a n inner barrel and an accelerating chamber. Gas is supplied to the system by t he blower assembly and mixed with particulate material. The gas/material mixtur e is transported through the mixing chamber into the accelerating chamber and through the outlet conduit. In other embodiments, the particulate material i s mixed with the gas in the accelerating chamber. Other embodiments of the system include only the mixing chamber, where a flow of at least one flowabl e material in the form of high or low pressure gas, liquid, and/or particulate s suspended within the gas or liquid enters either laterally or axially, forms boundary layer and laminar flows, and exits through the accelerating chamber .</p> |
