Microchannel Mixing in COMSOL

[@samantharobinson2700]

This was such a concise, clearly communicated tutorial with great production (audio and visual). Thank you so much, I subscribed.

The parametric sweep was awesome, very useful feature...thank you

[@Tibug]

So nice and well done and furthermore exactly what I need right now. Thank you!

[@navyasethu1404]

Thanks for the video... One such tutorial, I was waiting for.

[@maxwellconniff1189]

Awesome. Thank you. Just subscribed, all COMSOL microfluidics welcome.

10:52, around 4 mm Arc length, how can the concentration of a substance be negative? there must be an issue somewhere

[@Tibug]

It's numerics, not physics. ;-) The concentration gradient is huge at that point. I would expect some numerical overshooting without further fine-tuning.

Dear Sir Could you please if it is possible to simulate fluidized bed reactor solid-liquid with adsorption isotherm model

[@dr.mohanadm-ridha1130]

Thank you

Hi, I want to simulate a biological Methanation process. In a Pipe I have 2 inlets and 1 outlet. In the first inlet should flow in water and in the second inlet should flow in a (hydrogen/carbon dioxid) mix. my goal is to obtain methane in the output by a chemical reaction. Wich Physics do i need for this Process? Murat

Hi! can I ask you some help for a multiphase laminar flow?

Hello. Nice turorial. A short question: You are using an unstructured mesh where the faces and the direction of the main flow have a varying angle. I used an structured mesh and experienced a much narrower region where the species mix due to diffusion. Is it possible that the broader region of mixing in this simulation originates from numerical artificial diffusion due to high gradients between mesh face direction and background flow ? Thanks.

When can we use 2D model? I guess when the problem has a plane symetry , right ?

Please explain for 2 solutions. Where liquid liquid extraction take place.

[@abayomiadeleke834]

Thank you

[@jayeshmathur5981]

We can use 2 solutions here.
