Extensions ; Resistive : Resistive MHD describes magnetized fluids with finite electron diffusivity ( ). Source: Internet

Below a depth of about 1000 m, carbon dioxide is injected as a supercritical fluid, a material with the density of a liquid, but the viscosity and diffusivity of a gas. Source: Internet

Conversely, a low diffusivity leads to slower cooling and a larger HAZ. Source: Internet

However, for engine oil, convection is very effective in transferring energy from an area in comparison to pure conduction, so momentum diffusivity is dominant. Source: Internet

In a sense, thermal diffusivity is the measure of thermal inertia. citation In a substance with high thermal diffusivity, heat moves rapidly through it because the substance conducts heat quickly relative to its volumetric heat capacity or 'thermal bulk'. Source: Internet
