Hi, thanks for the great video! Could you possible make a savonius simulation inside a pipe? and derive power graphs and power coefficient graphs with RPM? That would be a huge help. There is a gap in existing videos!
Super useful video thank you :) I am having an issue though - when looking at the result in CFD Post the only flow with changing variables is within the rotating region, the rest of the flow is stationary. The streamlines also don't seem to appear. Any idea what I might've done wrong?
Modeling a fan in CATIA or Solidworks is gonna be hectic. I suggest you try openVSP where you give in parameters and the model is done. And then import it to Ansys
Even though it might be too late, what he did was ctrl+a (selected all faces), then deselected the outside faces to get the blade. You can also do it by use box select in face select mode
Listen here there will be no boundary conditions because we are simulating the effect of propeller blade on almost stationary air so propeller rotates it will suck in air and leave out

I did a lot of research on TH-cam but I couldn't find it, but thanks to you I found it, thank you.
this is actually very useful for me thanks a lot
Sir, in this you gave the mesh motion i.e angular velocity to turbine but how to calculate the rpm of turbine by giving the wind speed.

Which version of ANSYS are you using? I have ANSYS 16.0 and it looks quite different. What do I do?
bro what steps are you doing in 8.40 for selecting just the propeller because i triy to do it but the whole inner domain is delected.
Ctrl+A and then Ctrl+F all surfaces of the solid until only the propeller remains
@@irisdumutel3371 heyy is there any way i can contact you i need the same help , i am stuck here 😭
@@irisdumutel3371I didn't work out for me can you please help me?
Could please make a video of complete drone analysis please 🥺

why did you mirror and translate the object at the start?
what is the total simulation time it takes ?
Hi please can you do step by step exhaust fan simulation and Fan rotation animation for air
I followed exactly what you did but after the calculations part the propeller cylinder gets tilted
Ive noticed that my K and Epsilon are not converging how do I fix that?
Nice, but how calculate the rotation of turbine as efect from wind speed?...
Can you show, how calculate dynamic / static structure analysis of turbine blade on ansys
*& noise analysis in ansys
Assalaamu alaikum bro. Have you been able to do this please?
does the rotating disk have to be a revolve? I did it as an extrude
There are some ERRORs. Mainly in mesh and setup. This result is not valid. My main concern is the setup.
but when you have a rotating domain, are you not also artificially rotating any air that goes into that domain? or is only the mesh rotating?
Good question, I am wondering the same thing.
Olny mesh
which ide and tools used
Do you have any tutorial for modeling the geometry of the fan?

Hello
Where could I find the results in order to load the results ?
Do we have to mirror prop and then delete it
For multi propeller purpose
@@Bharathacad got a job for u
thank you i love you
How we can find Force caused by flow
Can i ask ur geometry bro?
Can anyone tell me the step he did on 8:40 min when he turned it transparent and selected the blade
have you found how to do it? mine's isn't worcking

What were the boundary conditions?
same question

Why is there no audio commentary?
Hey my simulation is happening for only initial and final time step. Where is the problem?
Solution control
Hi! Would you be willing to share this simulation file for personal use?
do you have propeller file 15x4? can give me?
Why did you not use LES ?
Too high of fidelity I guess
where is inlet?
iam getting this error when i start fluent setup: Error: Cortex received a fatal signal (SEGMENTATION VIOLATION).
Error Object: ()
Is it possible to share it's/STP file?

Hello! What did you do in time 8:40 ?
Select all
@@Bharathacadat 13:45 which choice did you select?
@@Bharathacad Pls send me your details got an urgent job for you.
@@Bharathacad HOW DO YOU SELECT ALL? AND HOW DO YOU DESELECT THE SURFACE UNTIL THE PROPELLER SHOWS UP?
@@hongngew2811 you can hide the faces that poses problem for the vizualization and select propeller by step

Can u upload cadd file sir
