Simple shear flow between parallel plates
Webb18 feb. 2024 · Rotational rheometers are the most commonly used devices to investigate the rheological behavior of liquids in shear flows. These devices are used to measure rheological properties of both Newtonian and non-Newtonian, or complex, fluids. Two of the most widely used geometries are flow between parallel plates and flow between a … WebbA first aspect (Aspect 1) refers to a formulation, wherein the formulation is a monophasic nano-disperse system comprising a) One or more phospholipid(s) selected from the group consisting of phosphatidylcholine (PC), phosphatidylinositol (PI), phosphatidylserine (PS), phosphatidylethanolamine (PE), phosphatidic acid (PA), phosphatidylglycerol ...

Webbconsider simple shear flow between parallel plates. A streakline is formed by injecting dye into the fluid at a fixed point in space. As time marches on, the streakline gets longer and longer, and represents an integrated history of the dye streak. In this example, streaklines are simply horizontal lines.

The non-linearity in the Ergun equation in fact arises from “local” losses — sometimes termed “shock” or “minor” losses — produced during laminar 'ow through the expan-Fig. 3.
Webb7 dec. 1998 · ABSTRACT. The three-dimensional deformation of an isolated drop in an immiscible liquid phase undergoing simple shear flow was investigated by using a parallel-plate apparatus. The drop was observed by video-enhanced contrast optical microscopy, either along the vorticity direction or along the velocity gradient direction of the shear flow.
