VAWT CFD simulation

Thank you for your insights. After conducting some research, we decided to follow the tutorial Drone Simulation Using Rotating Zones as a reference, as we wanted to analyze the flow simulation when the turbines are rotating.

Here’s the link for the updated project: H-rotor

We decided to test the H-rotor first for faster computability as well, and later on we will try to do the save to the Savonius rotor. Based on simulations, we have gotten couple of torques on various windspeed which is something we wanted to get as well to get the power output later on.

However, we are still in the somehow in the dark on the lift coefficients. Here are my questions:

  1. Is our force plot kind of reasonable values especially the Torque at various wind speeds?
  2. I am thinking of creating multiple force and moment coefficients for each blade as to test whether they will have different values in terms of lift. Is my idea somehow will work?

Thank you in advance. Any feedback or suggestions will be very helpful.

Btw, this is a base design (without dimple) since we will be comparing it to the dimpled designs if in case we are on the right track. TIA.

Best,
