It is not calibrated for general industrial flows, and does produce relatively larger errors for some free shear flows, especially plane and round jet flows.

Shear flows in fluids tend to be unstable at high Reynolds numbers, when fluid viscosity is not strong enough to dampen out perturbations to the flow.
13.
Whilst the model gives good approximations of viscoelastic fluids in shear flow, it has an unphysical singularity in extensional flow, where the dumbbells are infinitely stretched.
14.
In pipe flow and other wall bounded shear flows, there are intermittent puffs that are central to the process of transition from laminar to turbulent flow.
15.
John W . Miles suggested a surface wave generation mechanism which is initiated by turbulent wind shear flows based on the inviscid Orr-Sommerfeld equation in 1957.
16.
Although that theory does include linear transient growth, the focus is on 3D nonlinear processes that are strongly suspected to underlie transition to turbulence in shear flows.
17.
Some of the key notable features of hairpin vortices are how they interact with the background shear flow, other vortices, and how they interact with the flow near the surface.
18.
He has developed nonequilibrium simulation methods including the SLLOD algorithm for the study of shear flow, the Evans'method for heat flow, the color conductivity method for the determination of self diffusion.
19.
A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other.
20.
In fluid mechanics, the term " shear flow " ( or " shearing flow " ) refers to a type of fluid flow which is caused by forces, rather than to the forces themselves.
