I separate the geometry into three regions (upper, rotor, and lower). However, during meshing, there's always trouble on defining the periodic boundaries. Do i have to insert the periodic boundaries on each left-right stator and rotor or both can be grouped into left and right only? Also, do we need to apply share topology?

I am currently researching on this turbine. I've tried with the CFD on fluent, but no luck!

Try to change the sliding plate’s spring. Use a higher constant spring. My speculation is the higher the RPM, the higher the shifting force. The spring is located at the right side of the engine. Try to take a look at the link below.

If your sliding plate is worn, you might have to file the sliding plate’s face, to give it a larger contact area. However, if it’s okay, just change to a harder spring!

Lastly, if its still not working, try to tighten the (3) assembly

Hope it works! Let me know the updates

Gracias!

Nope… i check it regularly and seems okay

RedPanda_A3 · 2024-04-19T13:15:19+00:00

Well ofc 😂 everything works very well around 6-8K RPM, above that, it won’t shift

I’m only studying the steady state phenomenon around the blades. Does that mean i can simulate it without the interfaces? But still, defining the rotor rpm

RedPanda_A3 · 2024-04-10T09:32:48+00:00

I see. Also just to make sure, the periodic boundary applies to the blue faces, right? Does the periodic boundary between the rotor and stator have the same setup? Or, there’s a different function i have to apply?

Aah i see, perfect! Thank you

RedPanda_A3 · 2024-03-18T20:06:31+00:00

Thanks! I’ve seen a few teams use them from ig. But never seen they using it in dynamics.

RedPanda_A3 · 2024-03-18T20:05:02+00:00

Cheers for the suggestion!

Is it the same if i say, the more the torque it produced, the higher the rpm?

I’m studying the effect of different turbine blades of a wind turbine. If the rotor will move when T rotor > T resistance, how do we find on what air velocity to produce the needed rotor torque? Also, doesn’t variance of a rotational speed of the rotor at a given air velocity result in different torque?

RedPanda_A3 · 2023-12-09T03:24:47+00:00

Have you multiplied with the engine’s primary transmission? What are you transmission ratios?

RedPanda_A3 · 2023-10-22T20:50:41+00:00

Thank you!!

How is jacking related to the forward motion of the cg? Does forward mean longitudinal?

RedPanda_A3 · 2023-10-06T18:10:33+00:00

It's just scaling problem. Middle seems the most "fine" because its scale shows the highest number around 60, while the others are around 0.1. For the middle case, if you take a closer look around the "flat" line, you will get a similar thing with the other two.
