Summary (AI generated)

Now, I will explain the pressure and wall shear components present in the track. We began by validating the pressure component in detail. To achieve this, we created a pressure counter and compared the 2D axis symmetric research with the 3D research. The results are shown on the left and right-hand sides respectively. The air is present in the nose region and the ber in the tail region.

Both the 2D axis symmetric and 3D research obtained the stagnation point, and the relative error between the two in estimating stagnation pressure is less than 1%. Additionally, we can observe similar patterns in both the 2D axis symmetric and 3D sea simulation.
