Abstract:
1. A method of measuring solids deposition from a fluid sample, comprising: charging the sample of initial composition to a Couette device having interior walls, wherein the Couette device comprises an outer cylinder and an inner cylinder which define an annulus in the volume between the exterior surface of the inner cylinder and the interior surface of the outer cylinder, and wherein the fluid sample is contained within the annulus; subjecting the sample in the Couette device to an initial pressure, an initial temperature, an initial shear, an initial surface type, and an initial surface roughness while the inner cylinder rotates relative to the outer cylinder via a magnetic coupling with a prime mover and imparts Couette flow to the fluid sample; changing at least one of the pressure, temperature, composition, or shear of the sample, and at least one of the surface type or surface roughness of the device; and quantifying deposits on the interior walls of the Couette device.
