ANSYS CFD Tutorial: Fluid Flow over a Circular Cylinder - von Karman Effect

[@prachishah8357]

Amazing tutorial, very well explained, I could follow each step with so much clarity. Thank you :)

[@AngelineTewaTEDOUNO]

Very explicit tutorial, thanks sir

[@boyanpetrov9975]

THANKS A LOT FOR THE HELP!

[@amarsoni2832]

Amazing Sir🎉❤

[@mostafaahmadi4998]

Incredible tutorial. Thank you very much for your time and effort.

[@FelipeFadini]

That is awesome! During my college time I didn't have any professors with enough knowledge on ansys to show these simulations to us. I am doing one here as you did and so far everything is going fine. Do you have any videos similiar to this but with airfoils?

[@seshireddyvenna4355]

Nice exploration tq

[@ajmech]

How about a tutorial on Multi-phase flow ?

[@VipulKumar-bs5kz]

Commenting here to grab your attention. I appreciate the good work and was looking forward for tandem arrangement of 2 and 3 cylinders. There are barely any videos for 2 and 3 cylinder arrangement so u making one would be helpful.

[@theengineeringguide8332]

Yes I agree! I will try to get the video up by the end of the week!

[@f_forghan]

Nice video.. Could you tell me how to calculate the total force of hydrodynamic?

[@BarryJones8]

Excellent tutorial thank you for sharing. When looking at grid convergence, how do you pull the data from the analysis to create the comparison charts?

[@saroj4736]

sir reynolds number is to be calculated at the cylinder diameter or edge

[@jakubgolc9296]

great video, only drawback is that the volume goes up and down after cuts

[@joerivandesande1378]

I think the time step size should have been 0.004 instead of 250, because the von Kármán effect should not take this long to take effect.

[@gloriamarceladebarrosmorae5198]

How can I calculate acceptable values for time step and number of time steps if my diameter is another and I'm changing the velocity of the water flow for each simulate?

[@MADHUSUTHAN4072]

Let me know if you know

Dear Sir Please make video on fluid-elastic Instability behavior of circular cylinder

[@engineered.mechanized]

To simulate the acceleration of a thin tiny mm-scaled cylindrical pole under turbulent water flow, do I need to use CFD or FEA?

[@Engr-Hassanshehwarshah]

Dear sir Please tell us can be fluidelastic instability phenomena establish in ANSYS or not

[@livetoloveiist]

hello, i'm working on a graduation research project about vortex induced vibration on an oscillating cylinder, could you please give me the needed UDF or setup to let the cylinder oscillate ? thank you best regards.

[@muhammadzahirul235]

Can this be used in turbulence cases?

[@saravananudayar8110]

How to plot the Vorticity contour for the current problem ?

[@arbindacharya6465]

Sir can you please make a video on flow around an oscillating cylinder where the cylinder is oscillating in the y-direction... it's really necessary sir do help in this.

[@gloriamarceladebarrosmorae5198]

How did you define the outlet conditions?

[@rockrock3898]

This video is helpful but I have some queries.. regarding my 3d Fluent can u help with it sir.

#TheEngineeringGuide, Can you make a fluid flow tutorial for U tube Evacuated with a V shape reflector?

[@jude.k.okonkwo8968]

It is over 25 minutes and the calculation is not up to 50% done , why is it so?

[@hemantthakur211]

It will take atleast 1 hour you have set the process for every sec for every 4000 illerations
