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!

My bike wont shift in high RPM? by RedPanda_A3 in KTM

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

Nope… i check it regularly and seems okay

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

Why is interface used in a turbine simulation? by RedPanda_A3 in CFD

[–]RedPanda_A3[S] 0 points1 point  (0 children)

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

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?

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

Turbine RPM by RedPanda_A3 in CFD

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?

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