General binary diffusion coefficient calculation via Fuller methode
Information
Calculation of binary gas diffusion coefficients according to [Poling2020] and [Waermeatlas2013]:
\\[
D_{i,j} = 0.00143 \frac{T^{1.75}}{p M_{i,j}^{\frac{1}{2}}\left(\nu_i^{\frac{1}{3}}+\nu_j^{\frac{1}{3}} \right)^{2}}
\\]
Here \\(D_{i,j}\\) is the binary diffusion coefficient (\\(\mathrm{cm^2/s}\\)) of species \\(i\\) and \\(j\\), \\(p\\) is the total pressure (bar), \\(T\\) is the temperature (K)
and \\(\nu_{j}\\) and \\(\nu_{j}\\) are the atomic diffusion volumes of species \\(i\\) and \\(j\\). The values for \\(\nu_{j}\\) and \\(\nu_{j}\\) are tabulated in [Poling2020] and [Waermeatlas2013].
\\(M_{i,j}\\) is calculated with the molecular weights of species \\(i\\) and \\(j\\) in (\\(\mathrm{g/mol}\\))
\\[
M_{i,j} = 2\left[\left(\frac{1}{M_j}\right)+\left(\frac{1}{M_j}\right)\right]^{-1}.
\\]
