Learned a lot ! Awesome videos !
Thank you.
Great Video.
Thank you
Nice video. Nice presentation.
Glad you liked it
You are awesome. Please, could you simulate nanofluid in pipe by discret phase. Thank you so much
Thanks a lot, sir, can you do some samples about Supersonic Flights?
amazing, thaanks a lot
Thank you.
Amazing 👍
Thank you.
ممنون
please help me, I can't find the algorithm 4:32 in my ansys, after I change the method to sweep
Which version software are you using.
@@AnsysTutor 19
This is a new option only available in latest versions like ANSYS 20 R1, Ansys 19 R3
@@AnsysTutor I see, thank you
Sir there is error in my projection saying " some selection sets did not produce any new results". Please help me out
You might have a problem in named selections. Plz check that.
Can you tell me how to find the built-in case of FLUENT？I can‘t find it. Thank you!
You can find it in the supporting folder or you can export the case+dat file .
@@AnsysTutor Thank you for you answer.
Thanks... for the great videos, please make a video on 2d water jet impingement on a heated plate..
Will try to make a tutorial.
How do we simulate the similar flow applies to annular flow in both rotating inner and outer cylinder? Or can u make a video on that? Thank you and appreciated it
We already have a tutorial regarding this.
th-cam.com/video/i5hPpuCm85s/w-d-xo.html
sir one complete explanation and calculation as well as report preparation of airfoil must be done. Thank you
Will try to add one such tutorial.
May you please give a tutorial on how to use REFPROP Data base to select for example supercritical CO2 fluid as the working fluid
Will try to make a tutorial.
@@AnsysTutor That will be awesome. Thank you very much
@@AnsysTutor if you can use the structured mesh model of the dry gas seal that will be very helpful
can u draw flow over a sphere in a vertical direction using gravity
Will try to make a tutorial.
I followed all the steps in this video and I got the result when the inlet velocity is at 0.1 m/s. However, When I changes the inlet velocity from 0.1 m/s to 40 m/s, there was no rotational velocity developed. What is the reason? is there any relation between inlet velocity and velocity at the wall?
I think the velocity is high enough for the small geometry, which might be suppressing the effect of rotation. Which caused it hard to observe the rotation simulation.
@@AnsysTutor Thank you for your reply. However, I have an experimental setup for the same model and I am getting the effect of rotational speed in my experiment regardless of inlet speed. In my experimental setup, my inlet velocity is always higher than the rotational one. But in modelling, it is only showing the effect of rotational speed for a small range of inlet speeds. Can you kindly comment your views on this?
Can we use inflation with that O-Grid meshing?
Inflation option might not work with sweep method.
hi sir, how do we do a simulation wiht the turbine inside and in a straight pipe like this? any video u made before?
Currently there is no such video on this channel, will try to make one if possible.
Hi, can you analyze the flow of the plate heat exchanger ?
Yes
How could you simulate a fluid that reverses its direction regularly. I am currently trying to learn how to simulate an oscillating water column, in which the airflow direction reverses as a water level oscillates up and down, however there is very little information about this online.
You need to use dynamic meshing approach for such simulation.
What is the function of precision and double precision also what is contours?
Double precision results provide more accurate results than single precision. Contours are the graphical representation of the parameter that varies in the domain.
My FLUENT gives the error,
FLUENT application failed to validate the connection.
What should i do to resolve this, kindly help.
Is it for a specific file or for all files?
@@AnsysTutor it is happening for all the files. Any suggestions?
You should reinstall the software.
Sir iam new to cfd and my doubt is why do we use a solid cylinder as a pipe rather than a hollow cylinder?
that is the fluid domain. The pipe solid body has not been created. Its the only outer surface of the solid cylinder which denotes the pipe inner wall.
@@AnsysTutor ok sir so basically we are not concerned about the structure we are just making a path for fluid to flow?
It's the analysis of flow behaviour. We can also create the pipe body similar to the real life object, but for simplicity and to reduce the computation time, we only focus on the flow domain.
Ok sir Thankyou
Do we need inflation layer ?
If you don't want the sweep meshing, you can put the inflation layer option.
Can u provide details of ppt
Sorry, dont have any ppt of this tutorial.
Why use voice changer?
U r doing this set up and operation without giving any reason why u r choosing this kind of options and putting the value in set up ..how a learner could understand if u not mentioning reasons behind the choosing of different options in set up
We have explained some options in some of our old videos, so for sake of simplicity we just skip some of the explanation. If you have any doubt you can comment. We will try to answer if its as per our knowledge.
