Soret coefficient Soret coefficient[sȯ′rā ‚kō·i‚fish·ənt] (physics) A tabulated value used in binary thermal diffusion calculations in gaseous systems; expressed as D ′/ D = α X1 X2, where D ′ is the coefficient of thermal diffusion, D is the coefficient of ordinary diffusion, α is the thermal diffusion constant, X1 is the mole fraction of the lower-molecular-weight component, and X2 is the mole fraction of the higher-molecular-weight component. |
