Definition

quotient of the thermal diffusion ratio $k_{T}$ (thermal diffusion ratio), and the product of the local amount-of-substance fractions $x_{A}$ , $x_{B}$ (amount-of-substance fraction) of two substances $A$ and $B$ :

α_{T} = k_{T} / (x_{A} x_{B})

quotient du rapport de diffusion thermique $k_{T}$ (thermal diffusion ratio) par le produit des fractions de quantité de matière locales $x_{A}$ , $x_{B}$ (amount-of-substance fraction) des deux constituants $A$ et $B$ :

α_{T} = k_{T} / (x_{A} x_{B})
