Thank you for nice tutorial. I have one question. If you have only one 90 degree bend and one side is immersed in tank w say 100 L water. Other end of the tube is connected to pump with flow rate of 5 L/min. How do I solve such problem for shear calculation ?
Does applying flow physics on the model make the model only work on solids? Because I've made a hydrocyclone in Comsol but I only get results on the parts that I made solid? I thought it was because of the wall defined in the physics but I am not sure.
Hello thank you for the nice work, very explenatory. The tube is solid or empty? I am trying to reproduce the problem but I cannot take the same picture with the ribons. thanks
can you show a video about Weak contribution for adding additional term in turbulence model? or you can see this paper"Topology optimization method with finite elements based on the k-ε turbulence model" eq. 11-12 Thanks
Sir I am simulating argon gas flow through nozzle for the turbulent case.When I use steady solution I get the results but when I choose transient I get an error that last time step is not converged plz help
Is there a way to measure total flow as you would with a closed loop in amperes law? I would like to design different geometries to maximize overall flow in a system
Go to physics->add physics->select fluid flow->single phase flow->select turbulent flow->select k-e model in turbulent flow OR go to my laminar flow video to see the process and select turbulent flow instead of laminar. Hope this helps.
@@Ochkhuu_E you have to give some boundary conditions that will make the low turbulent, like you can use Reynolds Number and use the velocity that makes a flow turbulent for the given pipe dia
Good content. You explained in a very effective manner. Appreciate the effort.
Thanks Very much brother

I want to learn about absorption of ammonia in hollow fiber membrane do you have any video on it

The tube is the liquid volume

Thanks
Will Definitely Try.
Anyways can you post the paper link here

@@LearnEase01 sorry for late reply
Hi. How do you estimate shear stress at wall after solution is obtained ? I see only velocity and pressure as output. Thank you
I used turbulent flow add gravity in comsol but not convergence 😢
I had issues with mine it say undefined materials property so what is the solution now

Sir can you make one for pin on disc wear

Can we create this model on COMSOL or we must do import from other softwares?
Sir, may I get the file of this module?
nice one dude. where can i find the geometry file
you can easily create this using solidworks
HOW TO BUILD THE PIPE NETWORK PLEASE ?
Use Solidworks then import

@@LearnEase01 thank you but i don’t understand how to build turbulent?

could you please send the geometry on mail?
