Matlab: Create streamline animation

Matlab: Create streamline animation

In Matlab, we can use streamline animation to visualize the motion of the flow field. Streamline animations can show how particles in a fluid change over time and help us understand the properties and behavior of flow fields. This article will introduce how to use Matlab to create streamline animation, and attach the corresponding source code.

First, we need to define a velocity vector field representing the flow field. In this example we will use a 2D velocity field. Suppose our velocity field function is velocity_field(x, y, t), where xand yare space coordinates and tis time. The function should return a 2D vector representing the velocity for the given coordinates and time.

Here is an example of a simple velocity field function that represents a rotating velocity field:

function v = velocity_field(x, y, t)
    omega = 1;  % 角速度
    v
