1. Subscript AB denotes diffusivity of species A diffusing into species B. 2. A third type of MRI is based in the water diffusivity . 3. Equating these two expressions yields a formula for the diffusivity : 4. In a sense, thermal diffusivity is the measure of thermal inertia. 5. Where \ kappa \; is the thermal diffusivity . 6. Self-diffusivity is a measure of the translational mobility of individual molecules. 7. The eddy diffusivity coefficients for momentum and heat fluxes are defined as follows, 8. The diffusivity and solubility of gold into silicon substrate increases with rising bonding temperatures. 9. In turbulent flows, computational fluid dynamics also considers the effects of turbulent diffusivity . 10. This expresses the mean squared displacement in terms of the time elapsed and the diffusivity .
