Mixture diffusion coefficient #130

Closed tbridel closed 1 year ago

tbridel commented 1 year ago

Good morning everyone,

In an application I am building around thermo, I would need to compute the Lewis number of a n-components mixture - so basically my understanding for a mixture is that we can think in bulk as a first approximation and go for the following expression:

Le = thermal_conductivity / (rho_mass * mean_diffusion_coefficient * specific_cp).

I am using flash as per the recommendations found in the docs, so I find myself with an EquilibriumState but I can't figure out how to compute a mean diffusion coefficient for the mixture. Can you please advise ?

Thank you in advance !

Hi Thibault, Diffusion is not a feature supported by the Thermo library at this time, sorry. I'll let you know if it's added at some point. Cheers, Caleb
