diffusivity's Usage Examples:

Diffusivity, mass diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient.

In heat transfer analysis, thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure.

ratio of momentum diffusivity to thermal diffusivity.

The Prandtl number is given as: P r = ν α = momentum diffusivity thermal diffusivity = μ / ρ k / ( c.

dimensionless number defined as the ratio of momentum diffusivity (kinematic viscosity) and mass diffusivity, and is used to characterize fluid flows in which.

is a dimensionless number defined as the ratio of thermal diffusivity to mass diffusivity.

Diffusivity may refer to: Thermal diffusivity, diffusivity of heat Diffusivity of mass: Mass diffusivity, molecular diffusivity (often called.

magnetohydrodynamics which approximates the ratio of momentum diffusivity (viscosity) and magnetic diffusivity.

The thermal diffusivity of the base material plays a large role—if the diffusivity is high, the material cooling rate is high.

known as the eddy diffusion coefficient, K (also sometimes called eddy diffusivity, with units of m2 s−1).

number, which describes the relationship between momentum diffusivity and thermal diffusivity.

term defined as the ratio between the momentum eddy diffusivity and the heat transfer eddy diffusivity.

Schmidt number, Sc, which expresses the ratio of the momentum diffusivity to the mass diffusivity.

The diffusivity along the principal axis, λ1 is also called the longitudinal diffusivity or the axial diffusivity or even the parallel diffusivity λ∥.

laser flash analysis or laser flash method is used to measure thermal diffusivity of a variety of different materials.
