diffusivity

The parameter you are looking for is known as "diffusivity".

The higher the diffusivity (of one substance with respect to another), the faster they diffuse into each other.

Then heat-removal rate would depend of vapor pressure and diffusivity in air.

A major drawback of the method is for problems with large diffusivity the time step restriction can be too severe.

The rate of transport is governed by the diffusivity and the concentration gradient.

On the other hand, thermal diffusivity is changing the temperature as fluid moves up and down the fingers.

Thermal diffusivity is often measured with the flash method.

The higher the thermal diffusivity of the sample, the faster the energy reaches the backside.

The decreased surface tension and viscosity under these conditions also favor diffusivity.

Diffusivity of helium is 2.65 times faster than nitrogen.

Measurement of sorptivity and soil water diffusivity in the field.

Thermal diffusivity is a measure of the speed at which temperature waves can penetrate a substance.

In a sense, thermal diffusivity is the measure of thermal inertia.

The magnetic diffusivity is a parameter in plasma physics.

It can also be called the perpendicular diffusivity ().

This expresses the mean squared displacement in terms of the time elapsed and the diffusivity.

For the barrier to be activated, the addition must diffuse to the surface and so a suitable diffusivity is also required.

Diffusivity of a compound describes the rate at which it moves due to random/thermal fluctuations.

The diffusivity of a penetrant depends mainly on its molecular size.

Equating these two expressions yields a formula for the diffusivity:

Transport properties such as diffusivity relate to how rapidly molecules move through the polymer matrix.

Additionally, mean diffusivity (MD) measures the strength of white matter tracts.

The great benefit of this device is that it measures both thermal diffusivity and volumetric heat capacity.

The thermal diffusivity is calculated to 0.0105 ft/hr or 2.72x10 m/s.

The thermal diffusivity coefficient, represented as alpha, can be written as .
