Stationary Device Produces Homogeneous Mixture of Fluids 
Collection Manifold 
Inlet 
The problem: 
To design a device, without moving parts, that will 
produce a homogeneous mixture of two or more one-
phase or two-phase fluids. 
The solution: 
A device with helical passageways through which 
the fluids are forced into turbulent flow by the system 
pressure differential. 
How it's done: 
The device contains two concentric flow guides 
with helical passageways. The fluids to be mixed 
enter one end of the device through intake ports on 
an inlet manifold, and are forced through the helical 
passageway of the inner flow guide to a collection
manifold at the opposite end of the device. A reversal 
in the axial flow direction of the fluid then occurs 
as it passes through the helical channel of the outer 
flow guide. After passing through this channel, the 
mixture, which is now homogeneous as a result of 
the induced turbulence, is released through a dis-
charge port.
