6.1.2. Velocity Field

Try these first

1. 1.

   Define a velocity field.

   Hint

   Think about how speed can vary in different places.

2. 2.

   What are the components of a velocity vector?

   Hint

   Remember the Cartesian coordinate system.

3. 3.

   What does a velocity field represent?

   • A constant speed across all points
   • Speed variation at different points
   • A static fluid condition

   Hint

   Think about how speed might change from one area of a fluid to another.

4. 4.

   True or False: Streamlines, pathlines, and streaklines are the same for unsteady flow.

   • True
   • False

   Hint

   Reflect on how time changes affect flow representations.

5. 5.

   A cylindrical structure is submerged in a flowing river. Discuss how you would analyze the velocity field around the cylinder using experimental and computational methods.

   Hint

   Consider both physical experiments and simulation tools.

6. 6.

   An airplane wing experiences different pressure gradients at various angles of attack. How would you assess the changes in velocity fields and the resultant lift?

   Hint

   Think of how altering angles impacts airflow and pressure.
