Abstract
A fluid flow promoter for increasing and accelerating the flow of fluids through channels, and useful in marine propulsion and aeration of liquids includes 1) an outer shell including an inlet end wall, an outlet end wall, and a solid truncated wall, 2) a fluid inlet generally centrally located in the inlet end wall, 3) an inner truncated cone with an inlet corresponding to the outer shell inlet and an outlet corresponding to the outer shell outlet, disposed within the outer shell and comprising end and side walls defining a space between the outer shell and the inner cone, the end and side walls of the inner truncated cone being perforated to permit fluid flow therethrough, and 4) a plurality of secondary fluid inlets disposed in the end or side wall of the outer shell. The apparatus is also useful in increasing the thrust of rockets and other jet exhaust devices, and for moving light gases such as helium in modular helium reactors.
