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. ❤❤❤

[@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.

[@manikandanr7389]

Kindly send a video for air flow velocity profiles (uniform, linear-up, parabolic, half parabolic) used in cfd simulations. Kindly refer the journal "3D cfd analysis of the effect of inlet air flow maldistribution on the fluid flow and heat transfer performance of plate fin and tube laminar heat exchangers " and tell me how to do the project . Thanks in advance....

[@AnsysTutor]

Mail us the journal to [e-mail]

[@manikandanr7389]

Hi sir pls reply

[@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.

[@RenderLover]

that was aweasome" love it!!

[@AnsysTutor]

Thank you.

[@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

[@mitikuamanumesele3975]

it was definitely helpful. Thank you

[@AnsysTutor]

Thanks.

[@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?

[@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.

[@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

[@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.

[@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.

[@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.

[@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.

[@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.

[@ukasyahzulfaqar9991]

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

[@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.

[@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]

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

[@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.

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

[@NanoActuator]

Can you do this with UDF?

[@AnsysTutor]

No.

[@NanoActuator]

@@AnsysTutor Ok. Thanks anyway.

[@marwasaood1759]

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

[@AnsysTutor]

Start with the single core solver.

[@ctroy38]

epic tutorial

[@AnsysTutor]

Thank you.

[@saurabhgoswami4570]

what is your ansys software version

[@AnsysTutor]

20R1

[@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.
