What does FI stand for?

On the other hand, the rheological properties of a nonisothermal non-Newtonian fluid may have an important impact on the flow instability and the subsequent nonlinear growth of the finger structures.

Although the specific causes of migraines are still unknown, the main contributing factor seems to involve blood flow instability in the brain.

Banks (2002) also introduced a number of different events that might lead to flow breakdown: (1) macroscopic flow instability, which occurs when fluctuations in flow and density evolve to the point where they trigger irreversible decreases in speed (2) microscopic flow instability, which appears during normal interactions of car following (3) flow disturbances resulting from vehicle maneuvers, such as merges, lane changes, and weaving (4) changes in roadway geometry (e.

According to the original article, no flow instability was observed in the range of experimental flow rates, and the isothermality was assumed in the FEM calculation (28).

The two most important types of problems are uneven layer thickness across the width of multilayer fims, and interfacial flow instability, manifested by poor optical properties and/or poor appearance.

If the flow rate exceeds limited velocities, explosive bubbles blast the source liquid out of the vessel and into the downstream piping, forcing the use of phase separators which lead to increased particulate, condensation, and flow instability.

1] and forms an obvious turning point, which is the onset point for the flow instability with oscillatory stresses.

[FIGURE 2 OMITTED] Flow instability of yield-stress fluids can result in branched fingering of the fluid as observed by McCloud and Maher and Lindner et al.
