In people’s common sense, two ships in the process of traveling cannot be driven side by side. This is not only the captain’s experience, but also contains more scientific reasons. In order to facilitate understanding, a small experiment with a ping-pong ball well verifies the phenomenon that two objects will continue to approach when flowing through high-speed liquid.
There is a very simple science behind this: the velocity of the fluid affects the pressure on the surface of the object.
To reveal the scientific reasons for this process by means of fluid analysis, the following key links and steps are required.
Step 1: Create a 3D model.
In this example, the corresponding analysis model has been created by SOLIDWORKS software
Step 2: Set the corresponding analysis boundary conditions for the model
In this example, we need to focus on two target points, the entry velocity and the analysis target.
Step 3: Interpret the Analysis Results
Through the static pressure item of the surface view, the force distribution of the table tennis can be clearly obtained. The outside is large and the inside is small, causing the balls to eventually move close to each other, or even collide.
