Nice 👌
Wow very helpful
Helpful myan
I'm working on this type of turbine for my final year mechanical engineering project
Awesome
Hi man, I can't understand why we are assuming that at an angular velocity we will have the most torque value possible.... how we can predict that in a real prototype the turbine will achieve that velocity...what if it can't get there?
What should you recommend to solve this problem ...
Firstly, we have calculate the the max and Min velocity of test ring with including both of runners. Then , we have the max and Min radius from our test ring design. That way can calculate angular velocity. Yes, it can relate the real protype for particular mass flow rate because angular velocity for particular always constant . In real test we can easily get angular velocity and torque as output . But in simulation we have assume that which possible value of angular velocity is appropriate to produce particular torque.
Yeah, you are right man, well thanks a lot, your video is amazing, you helped me a lot 🤝, just one more question, in the video with single stage turbine, you picked angular velocity "4" because it was the higher value in the range of water velocity without a turbine?
I'm working in this project for my final grade in Uni. Thanks for the answer 👍
Really nice but i have a question. Why didn't u select inlet as velocity inlet?
U can take velocity as a inlet . There is no issue.
As in my project I have selected mass flow rate as input so in this video select as input otherwise there is no issue to choose velocity as a inlet
@@amitsvlog5274 Have you created an animation with ansys? in which turbine is rotating?
I haven't the animation video right now but I will show it in my next video
sir, why the torque i get increases as the rpm increases? as we know, the torque value should decrease as the rpm increases. I've followed the steps you described, but my simulation results are as I described. Can you explain why my simulation results are like that?
I think you should check the mesh analysis. This mesh analysis is good for my model so, please focus on mesh analysis.
Can you send me your cad model

Sir, what is the meaning of negative torque in your result? And is it normal?
Negative only represents the direction . we should go for further calculation by taking magnitude only.thanks
@@amitsvlog5274 Ok thanks Sir, my colleagues and I are working with the project related to multistage vortex turbine too. We followed the instruction on this video with 3 stages, but we got the result of torque with high variation. For example, in some data it showed Torque around 0.005 J, but in some data it showed until 5000 J although the variation of rpm is small. What is the possible cause and solution for this Sir?
and which one is better to model multistage rotor between steady case like you did, or transient using sliding mesh?
Thanks
you should check your mesh. If the mesh is okay then the result will not be varied much.
@@amitsvlog5274 ok thank you and which one is better to model multistage between steady and transient Sir?
@@elluthfi plz follow this instructions while putting the data ruclips.net/video/vwFLn1OfFBk/видео.html.
it depends on your full knowledge about transient and steady. both will be okay .
From where you got the 2020R1 crack. Please message me the link
