Question

What is the flow pattern?

Plot the velocity field, potential field, and streamlines.

Please explain it in detail.

 

**Exercise 3:** Determine the two-dimensional stream function corresponding to \( \phi = A \ln (r/r_0) \), where \( A \) is a constant. What is the flow pattern? Plot the velocity field, potential field, and streamlines. **Explanation:** This text outlines a task in fluid dynamics, specifically asking to find a stream function for a given potential function in a two-dimensional flow. 1. **Stream Function (\( \phi \))**: A mathematical function that describes the flow characteristics. Here, \( \phi \) is given by \( A \ln (r/r_0) \). 2. **Determine the Flow Pattern**: Analyze the stream function to understand how the fluid flows in space. 3. **Plot the Velocity, Potential Fields, and Streamlines**: - **Velocity Field**: Represents the speed and direction of fluid at different points. - **Potential Field**: Contour plots illustrating regions of equal potential. - **Streamlines**: Curves that are tangential to the velocity vector, representing the path followed by particles in the fluid. Understanding each component involves applying mathematical techniques to solve for the stream function and then using graphical methods to plot each field.
