Dear Shavan, really appreciate your video and time. I have a problem with this example. Could you please explain why, in this model, water just rises instead of oscilating and reaching a stable height according to Young-Laplce equation?
Hi, thanks for the great tutorial. Unfortunately when I'm setting the Wall lubrification model to Tomiyama et al I'm getting "A valid 'turbulent dispersion coefficient' (burns-et-al or lopez-de-bertodano) must be set for the appropriate phase-pair when selecting the tomiyama-et-al wall lubrication model." Do you or sombody else have any tips on how to solve this? It would be really really appreciated!
Hi, nice demostration. I have two problem: 1 ) can we give variable surface tension base on concentration gradient? , and 2 ) Can we give three phases in multiphase model? Let me know what u think.
1. In Fluent you will have to write a UDF to make your surface tension dependent on concentration gradient. 2. You are able to model up to 10 phases using Fluent multiphase.
How to setup test case for 3 phase problem .......like water+oil ( separator) and air is used to separate them with sparger ............ whole problem is solved using multiphase setup or with DPM + multiphase flow............. Thank U for videos and notes.
Hii, Can you upload the video on simulation of gas seperation on solid surface (desorption) on heating & deposition upon cooling (adsorption) phenomena & transient model of pressure variation in it ???

Hi Shavan, can u make a video on jet break-up and spray formation when liquid jet gets injected into a quiscent atmosphere.

Hi, Can you please make a tutorial on concentrated solar collectors like parabolic trough or parabolic dish

Nice work
Hi Shavan, Can you please make a video on Heat pipe with wick and working fluid is water?
Hi Sridhar, did you do the heat pipe simulation with wick?
Hii,

Just a quick question about the model. why did you use eulerian model? why not VOF ??
Great help! Thank U sincerely!
My center column would not go up even tho the wall adhesion is on and set to 30 degrees
Did you solve the problem? I want to know the solution, too.
@@damlee9856 No I have not. I am using the 2022r2 ansys solver
