Savonius (Two-Blade) Wind Turbine, CFD Simulation (3-D) Ansys Fluent Training

In this project, a 3-D Savonius Wind Turbine (with two blades) has been simulated, and the simulation results have been investigated by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The savories wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from wind energy. The turbine consists of several curved airfoil blades mounted on a rotating shaft or framework.

In this type of turbine, the main rotor is positioned vertically. The most important advantage of vertical wind turbines is that they do not need to be adjusted to the wind direction and can also be used at low altitudes.

The three-dimensional geometry of this project has been produced with Spaceclaim software. Two blades with 350mm diameter and 25mm thickness, and 800mm height located in a rotating circle with 1000mm diameter surrounded by 8000mm*4000mm*800mm cuboid were sketched.

We carry out the model’s meshing using ANSYS Meshing software. The element number is 494,456. Also, the transient solver is enabled due to the present problem in which we have used the mesh motion option.

Savonius Methodology

In this project, a two-blade Savonius wind turbine was simulated using mesh motion in Ansys Fluent software, and the results were investigated. Air enters the fluid domain from the inlet with 10m/s velocity while the turbine rotates with a constant angular velocity of 40rpm.

Our final goal is to illustrate the pressure and velocity distribution and animate the fluid motion behind the turbine. Moreover, the SST k-omega model can solve turbulent fluid equations due to its advantage in capturing fluid flow patterns near and far from the blades’ surfaces.

Savonius Conclusion

After the solution, two-dimensional contours related to the pressure, velocity, and streamlines are obtained. Figures in this product gallery show a variety of contours of fluid changes during its motion through turbine blades.

According to them, pressure and velocity distribution are distinctly different in the inner and outer blades. The flow enters the domain with 10m/s velocity.

After the collision with the inner blade, a tremendous pressure increase occurs, so the velocity magnitude decreases and reaches zero at a point known as stagnation point; This may cause negative torque that is not our preference.

On the other hand, the outer blade experiences a high-velocity flow on its back, which tends to push the blade clockwise.

    I’m curious, could you elaborate on the advantages of using the SST k-omega model for this particular simulation?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The SST k-omega model is advantageous for simulating turbulent flows, especially around complex geometries like wind turbine blades, due to its ability to capture the flow both in the near-wall region and in the far field. This is essential for accurately predicting the performance of the Savonius wind turbine, as it ensures that the effects of turbulence are well-represented where it matters most, leading to more reliable predictions of pressure distribution and torque on the blades.

    What model parameters have you tuned to achieve more accurate simulation results for the Savonius Wind Turbine?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this simulation, we have tuned the following parameters for accuracy: the element size during meshing for better resolution near the blades, the SST k-omega turbulence model settings for capturing the flow around the turbine accurately, the time step during the transient analysis for capturing the dynamics of the simulation effectively, and proper setting of rotational velocity and inlet wind speed. Fine-tuning these parameters helps accurately predict the performance of a two-blade Savonius Wind Turbine.
