Table

Diffusivity of A in N
Molar fraction of N

Molar fraction of A in the mixture

Output data

Diffusivity coefficient of A in the mixture

Description

Calculate the diffusivity of a component in a gas mixture using Wilke's equation:

DA,M=1∑YN′DA,N D_{A,M} = \frac{1}{\sum{\frac{Y'_N}{D_{A, N}}}}
YN′=yN1−yA Y_N' = \frac{y_N}{1 - y_A}

Where:

  • DA,ND_{A,N}: Gas diffusivity of AA in the NN-th component of the mixture;
  • yNy_N: Molar fraction of NN in the mixture;
