In this simulation, we observe the fluid flow behavior at a Reynolds number of 300. The contour plot illustrates the streamline patterns and vorticity distribution, highlighting the intricate interactions between the fluid and immersed boundaries.
For a Reynolds number of 1000, the contour plot reveals more complex flow structures, including vortices and wake regions. This plot demonstrates the solver's capability to accurately capture the dynamics of higher Reynolds number flows.
At a Reynolds number of 1000, the fluid flow exhibits turbulent characteristics. The contour plot provides a detailed visualization of the turbulent eddies and flow separation, showcasing ImmerseFlow++'s robustness in handling highly dynamic fluid behaviors.
