Thank you very much, sir, for such a nice video
This is a very detailed and nicely done video explaining a lot of doubts. In the video you mention that you have created a udf for nano particles in a previous video. I can't find it. It would be amazing if you could share it.. Good Luck.
For and foremost thank you shavan'' for making such an informative sessions on CFD.
1.) I appreciate for addressing my question on Cell volume.
2.) i want to know on what basis you considered the water property equations while writing udf [please share reference for water property equations].
3.) Those UDF equations valid for only nanofluids with spherical particles what if for cylindrical particles
4.) How far considering nano-fluids as single phase will be accurate
5.)Next time could you please do video on " how to check the volume fraction of vapour, if a fluid is flowing in a pipe".
In many of research publications it is acclaimed that the variation between multiphase nano fluid and single phase nano fluid is low
For vapor I have done one tutorial on water falling onto hot walls, please look into the tutorial
thanks for tutorial. I wonder that udf can be hooked up without any issue or without using M/s visual studio. I, therefore, stopped using UDF after 2014.
Thank you Shavan Technology for the insightful video! I wonder about your UDF equations. Where did you get the k_f, U_f, and rho_w equations from? I have read your publication but still haven't understood your function definition.
Thanks in advance! Looking forward for your response.

Sir ... Good evening 🌅
I wanna ask you a some questions
When I want to enter the properties of nanofluid the ansys demand from me to enter the viscisity ....how can i do it ?
what is the format or software tutorial for creating a user-defined format?
Sir, is it possible to do simulation on nano refrigerants, by adding nano particles in compressor oil. If it is possible kindly help me.
why I can't calculate ,it shows that
Divergence detected in AMG solver: pressure coupled
Divergence detected in AMG solver: k
Divergence detected in AMG solver: epsilon
Divergence detected in AMG solver: temperature
I really liked your video. You mentioned in this video that you have earlier made a video explaining the udf you have used, but I couldn't find it. It will be really helpful if you share the link to that video. And can you please make a video for simulation of nanofluids without considering it as a single-phase fluid.
Yes, definitely
Great video @@shavantechnology3472. Would you are attach the file .txt done in this tutorial?
¿ What is desired y+ in mesh ? ¿ What it is ?
it was really useful. is it possible, put a video that solve nano fluid with a mixture model?
I share your request for this. It will be very helpful
sir, can you please make a video on how to write a udf for non uniform (gaussian ) heat flux on tube wall. thanks!
I appreciate your effort and expertise on this very dynamic and evolving field. I believe a lot of people would benefit from it. Pls, can you share the reference from where you obtained the expression for rho_w (temperature-dependent) i.e rho_w=(753.2+(1.88*T)-(3.57e-3*T^2)). Someone propose and request for similar work with mixture model. I second this request.
Thank you and wish you best luck
u can find the publication link in the description and two phase nano fluid is also performed in my other video using eulerian approach.
And I request you to ask your friends also to subscribe the channel
Why we need to go for UDF , we ca simply define the expression driectly into the Material data as function of T and volumetric ratio, it would been an simple approach and pople can understand easily but nice try.
Thanks a lot my lord, if can send me your mail adress
