ANSYS Fluent Tutorial | Parabolic Inlet Velocity Profile That Varies Over Time | Without UDF | CFD

[@fofomrk5467]

Thank you for the high quality, best I've seen so far, clear audio and visual.

[@AnsysTutor]

Thank you.

[@moparikshya]

I have learnt a lots of things from this channel. Thank you Ansys's Tutor 🤝

[@AnsysTutor]

Thank you.

[@nanh7350]

Thank you for every video you make from start to finish I really benefited, please continue. 👏👏

[@AnsysTutor]

Thank you. ❤❤❤

[@AkashSingh-b1t]

Thanks for such a nice explaination what if we don't have function for temporal variation instead we have variation of amplitude wrt time at discrete points in time?

[@AnsysTutor]

Watch our tutorial on pulsating flow,it might help.

[@piyushbhatt7309]

Thank you, sir, for this wonderful video, how can we give the wall (boundary of flow) a function just like in this case inlet is given a function.

[@AnsysTutor]

Yes, we can put variable temperature bc on the wall.

[@piyushbhatt7309]

Sir for variable bc with respect to position say flow is taking place in x direction and boundary on y and we want to put bc chane according to x and time then

[@ademolajayeola9846]

Thanks!. Can you model a flow blockage scenario in the flow channel of say: 3 by 3 rod bundles and produce some plots from it?. Please i would appreciate.

[@AnsysTutor]

In flow blockage how can we generate the velocity profile. Please describe more about your simulation.

[@somannacs]

nice video! Could you tell what is the need or importance of 'Parabolic inlet velocity'?

[@AnsysTutor]

Its a fully developed laminar flow, if you want to put such type of scenarios then you can use such.

[@e-cfd8639]

Great Work Can you please let me know how to make square pulsating inlet condition ?

[@AnsysTutor]

You can use UDF , or use the transient table data input method.

[@RenderLover]

that was aweasome" love it!!

[@AnsysTutor]

Thank you.

[@Ginneko93]

Thanks, How can I use my data from the velocity profile (transient table) in the parabolic inlet Velocity Profile? I tried with the profile data in umax but it doesn't work.

[@eichannel7047]

Excellent

[@mitikuamanumesele3975]

it was definitely helpful. Thank you

[@AnsysTutor]

Thanks.

[@ctroy38]

epic tutorial

[@AnsysTutor]

Thank you.

[@studypurpose7804]

hi, is there link for dust simulation of various particles sizes in tunnel ? Thanks a lot.

[@andrecardoso9906]

Hi, why do you multiplicate the "sin(omega*time)" by 0.1? The sum of 1 after the sin operation makes sense to avoid reverse flow, but that 0.1 after the sin I didnt understand

[@AnsysTutor]

That is the amplitude of the sin function.

[@ukasyahzulfaqar9991]

Just wanna ask. How you get the value for umax?

[@ammarlaichi8474]

sweep method does not work in copper tube, we have two body solid and fluid, what do you do now?

[@AnsysTutor]

It's only applicable for a single body irrespective of the material.

[@marwasaood1759]

I did all the steps exactly like the video. But I have a problem that the speed diagram does not appear on the screen so that I can follow the solution only scaled Residual s

[@AnsysTutor]

In monitors select the report plot. This procedure is shown in the tutorial.

[@ghifarihaikal3006]

what should i change if my velocity is 11.96 m/s? I tried to replace the umax but the results report the velocity reaches 170 m/s so reversed-flow occurs then omega is the time if i keep 5s it doesn't matter if i simulate flowtime more than 10 minutes?

[@haditannous6222]

How can apply that to an inlet that is far from the coordinate system?

[@AnsysTutor]

You need to do setup for this in the UDF.

[@dheerajsingh0390]

Hi, i need to put a fully developed velocity profile for a rectangular duct. How can I do it? kindly suggest. Thank you.

[@abdulmahroof.n5108]

during initialisation in audio you are saying to select allzones but actually you are selecting inlet...

[@AnsysTutor]

You can take any zone that does not matter.

[@abdulmahroof.n5108]

@@AnsysTutor ok,thankyou for your reply

[@NanoActuator]

Can you do this with UDF?

[@AnsysTutor]

No.

[@NanoActuator]

@@AnsysTutor Ok. Thanks anyway.

[@marwasaood1759]

Hello, I am doing a simulation of the pipe. Water with a constant heat flux in the case of the transiet. The wall does not heat up. Can someone help me?

[@AnsysTutor]

Check the meshing and boundary conditions.

[@johnbohn3626]

Sir graph is not showing in my screen after following the same steps. The initial and final figures are same

[@AnsysTutor]

Have you selected the " report plot" option.

[@johnbohn3626]

@@AnsysTutor sir I got different graph plot from yours

[@johnbohn3626]

I am not getting the inlet velocity profile parabolic

[@AnsysTutor]

Have you done the geometry in the same plane as shown in the tutorial?

[@johnbohn3626]

@@AnsysTutor yes

[@RR-kx6dt]

can it be done for 2d model as well with every other action being same?

[@AnsysTutor]

We also have a 2D tutorial regarding this.

[@saurabhgoswami4570]

what is your ansys software version

[@AnsysTutor]

20R1

[@marwasaood1759]

When you choose 8 process solver an error occurs f1 process cannot be started

[@AnsysTutor]

Start with the single core solver.
