In physics, the nu symbol denotes the frequency of waves, wave-numbers and spatial frequency while in fluid mechanics, it represents kinematic viscosity and in statistics, it represents the degree of freedom. (sieradskillc.com)

Furthermore, the additional term $\alpha \partial _t\mu $ corresponds to a parabolic regularization of Eq. ( 1.2 ), while $\beta \partial _t\varphi $ is the viscosity contribution to the Cahn-Hilliard equation. (springer.com)

is not a constant but varies as a function of flow speed, flow direction, object position, object size, fluid density and fluid viscosity . (cloudfront.net)
The shaft rotates at a speed $\omega$ (in rad/s), and the oil has a density $\rho$ (in kg/m$^3$), a viscosity $\mu$ (in kg/ms), and a thermal conductivity $k$ in (W/mK). (overbrace.com)
A , B and C in ( 1.1 ) are constants depending on mass and area of the plate, stiffness of spring, fluid density and viscosity. (springeropen.com)

Extensional viscosity (also known as elongational viscosity) is a viscosity coefficient when applied stress is extensional stress. (wikipedia.org)

The shear viscosity is a property of liquids that can be determined easily by experiment. (gromacs.org)
When the shear rate is too high, the observed viscosity will be too low. (gromacs.org)

Extensional viscosity is defined as the ratio of the normal stress difference to the rate of strain. (wikipedia.org)
Flow characteristics can be characterized by the Froude and Reynolds numbers, which represent the ratio of flow speed to gravity (buoyancy) and viscosity, respectively. (platinumfenc621.cfd)

Medium viscosity determines the rate at which sound is attenuated. (wikipedia.org)

In general, a simulation length of 100 ps is enough to obtain an accurate value for the viscosity. (gromacs.org)

The viscosity is also an important property, since it influences the rates of conformational changes of molecules solvated in the liquid. (gromacs.org)
It is ideal for use with most low-to-medium viscosity liquid applications and features a range of filling options and speeds. (advanceddynamics.co.uk)

This method converges very slowly 149 , and as such a nanosecond simulation might not be long enough for an accurate determination of the viscosity. (gromacs.org)
GROMACS also has a non-equilibrium method for determining the viscosity 149 . (gromacs.org)
With the aid of Moudafi's viscosity approximation method, we prove a strong convergence result for the sequence generated by our algorithm under some mild conditions. (springeropen.com)

Using a (short) cut-off results in large noise on the off-diagonal pressure elements, which can increase the calculated viscosity by an order of magnitude. (gromacs.org)
