Ansys Fluent: Vertical Axis Wind Turbine Using Dynamic Mesh.

- This video shows how to simulate the motion of a savonius wind turbine using the dynamic mesh tool in Ansys to rotate and inner domain containing the turbine walls.
The mesh should have more elements for a better simulation, but I think this is enough for demonstration purposes.

This is definitely the Best TH-cam channel on ANSYS fluent
Wow, it is very good video. It will help me to learning Ansys Fluent. Thank you so much!
You're welcome.
Loved the background music
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! And it is very important for me and other people I guess. It would be really life saving and a good addition for this amazing channel
Add wind-deflectors to the VAWT-model. It will eliminate the drag and redirect the negative wind into positive.
Example from real a test VAWT with(out) deflectors: Wind 2 m/s, without deflectors 0 rpm, with 215 rpm
Wind 5 m/s, without deflectors 286 rpm, with 509 rpm
Wind 10 m/s, without deflectors 480 rpm, with 813 rpm
can you share the ansys file?
@@sandippoudel5160 search for "The most powerful vertical axis windturbine (VAWT) on earth"
Is there any article or report regarding this?
@@sandippoudel5160 Did you find the recommended video? It's enough for me to know that only VAWT with deflectors have the highest efficiency. Without deflectors they lose not only available air flow, but also the drag slows them down. The only exception (so far) would be the "Bi-rotary Hilton wind system" by hiltondynamics.

Hello do i need to do anything in the setup animation before solving so i can see the rotation or no need i can see it in solution?
Thanks for this video. can you clarify @14.00 , how you have taken dynamic meshing zone.
HI Fluent Setup! I like your videos a lot and they've been an excellent guide on Fluent. I am having some trouble on a particular VAWT case. Can I contact you for some assistance?
What method should I apply for two perpendicular axis of rotation. Where the latter axis revolve around the another axis. Pls 🙏
hello sir it is very good video. Please explain how get the rpm of turbine from the same setup.
Hello, I'm just new in ANSYS. Is it okay to use this method for extracting the data for torque?
my turbne dont movealso its mandatory add extra regions both sides of the interior?
Hi , can you please tell me what happened to the turbine wall that you initially created ? I saw that you subtracted from the small cylinder around it but in mesh when you had a cross section it seemed like the rigid body of wall is subtracted from it ? or when you moved to design modeler it counts the turbine wall and the cylinder around it one item
could the model be done in ansys space claim?
wow only 320k elements for such a complex geometry. what is your computation time?
hello..
Please explain how get the rpm of turbine from the same setup
do i need to sketch here or can i uplad astep file
What exactly does the formula you wrote in the velocity magnitude section mean?
Hi, I used that formula so the inlet velocity transitions slowly from a value of v=0 at t=0, to a value of v=v0, at a large enough value of t. If I had used a constant velocity, you would have seen the velocity transition from v=0 at t=0, to v=v0 in just a few time steps. And that wouldn't look realistic.
Hope that clarifies it.
@@fluentsetup1232 Got it, thank you so much. Your content is definitely very helpful. Thanks for everything. Best of luck!
Could you help me with my VAWT simulation ?
What's the music of this video please ?
Hello, how can I calculate the rpm of the turbine in Ansys fluent? I really need that data to optimize the design.
you can find torque of the rotating body. refer this video th-cam.com/video/b9obQ6FUj5E/w-d-xo.html
@@vivekjkumar5797 in the link given by you the geometry of the blade is different, so how it will apply to curved type blade? pls explain.....
How to find RPM of rotar only with inlet velocity
Hello, please wich file format you choose to export the geometery to Ansys software ?
I use .stp, but there's a whole lot of other format that would work too. You can google whatformat are compatible with Ansys.
@@fluentsetup1232 please, could you send me your email address?
Hello! Why you dont use smoothing, layering, remeshing in Dynamic Mesh? Can you explain when to use smoothing, layering, remeshing?
Hi , can you please tell me what happened to the turbine wall that you initially created ? I saw that you subtracted from the small cylinder around it but in mesh when you had a cross section it seemed like the rigid body of wall is subtracted from it ? or when you moved to design modeler it counts the turbine wall and the cylinder around it one item
hello, i want a one help, do you find the power graph with various rpm. if you know it, can you kindly share to me. thank you for seeing my comment

Please give a link for geometry
Assalam o aleikum, can you send me this file , I want to do some work on this, please.
Why did you use the formula when giving the velocity value?
8 [m s^-1]*(1-exp(-Time/0.5[s]))??
I think because he wants that the velocity to increase gradually until gets 8 [m/s] following that function. it's not necessary if you want a constant velocity on inlet only put 8[m/s]

How can I calculate power and tourqe of the turbine ?
you have to use the fluent console to find torque.
check out this video th-cam.com/video/b9obQ6FUj5E/w-d-xo.html
Bro is the torque and rpm of 2 dimensional VAWT fluent simulation result same with 3 dimensional?
Does ANSYS student support this calculation?
