Flow development chamber
First Claim
1. A flowable material handling system comprising a flow development chamber, an inlet pipe coupled to the flow development chamber, and an outlet pipe coupled to the flow development chamber, the flow development chamber comprising:
- an outer chamber an inner barrel located inside the outer chamber to define a flow space between the outer chamber and the inner barrel;
an inlet portion of the outer chamber the inlet portion having an inlet opening configured to allow flowable material from the inlet pipe into the flow space between the outer chamber and the inner barrel;
a deflector adjacent the inlet opening to direct flow tangentially around the inner barrel;
wherein the inlet pipe, the outlet pipe, the inlet opening and the deflector are arranged to set-up a flow pattern in the flow space such that substantially all of a flowable material flowing through the inlet opening into the outer chamber will circulate around the inner barrel from a location adjacent the inlet opening to an outlet end of the outlet chamber, and flow out through the outlet pipe.

Abstract
A system and method for conveying flowable material 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, an inner barrel and an accelerating chamber. Low pressure air is supplied to the system by the blower assembly and mixed with particulate material. The air/material mixture is transported through the mixing chamber into the accelerating chamber and through the outlet conduit. In other embodiments, the particulate material is mixed with the air in the accelerating chamber. Other embodiments of the system include only the mixing chamber, where a flow of at least one flowable material in the form of high or low pressure gas, liquid, and/or particulates suspended within the gas or liquid enters either laterally or axially, forms boundary layer and laminar flows, and exits through the accelerating chamber.
