We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Prashanth,

Thanks for those links, I wasnt aware of all of those cases but unfortunately none of them demonstrate the phenomena I am looking for. I think in both of the cases you linked the main driver for mixing is from the turbulence generated by the flowing fluids. 

The case I am considering is trying to eliminate all impacts from turbulent flow to demonstrate the impacts of only Fickian diffusion (Fick's laws of diffusion - Wikipedia). 

As described above, there is a simple analytical solution for simple systems but I was hoping i would be able to use this to validate to use the model for more complex geometries.Â
