WebOct 18, 2024 · The Soret coefficient S_T=D_T/D determines the concentration gradient in the nonequilibrium steady state. For sufficiently small Soret coefficients S_T \ll 1/\delta T, as prevalent in our experiments, the product c (1-c) can be assumed constant. The transient beam deflection signal is fitted by an analytic solution of Eq. WebOct 19, 2024 · The Soret coefficient indicates whether the components diffuse toward hot or cold region and provides the separation degree of the components between hot and cold regions. cleveland tennessee mayor
