functionmultiComponentDiffCoeff
Information
Multicomponent diffusion coefficient for the limiting case of a single dilute component diffusing into a homogeneous mixture according to [Poling2020]. \\[ D_{i,m} = \left( \sum_{\substack{j=1 , j\neq i}}^{n} \frac{x_j}{D_{ij}} \right)^{-1} \\] Herein, \\(D_{ij}\\) is the binary diffusion coefficient of the components \\(i\\) and \\(j\\).
