10.2.2. Incompressible Viscous Flow Between Plates

Try these first

1. 1.

   Define Incompressible Flow.

   Hint

   Think about how fluid density changes during flow.

2. 2.

   What is a velocity potential function?

   Hint

   It relates to how we express velocity in simpler terms.

3. 3.

   What is the primary characteristic of incompressible flow?

   • Constant Density
   • Variable Density
   • Low Viscosity

   Hint

   Remember the definition of incompressible flow.

4. 4.

   True or False: Velocity potential functions can be applied to rotational flow.

   • True
   • False

   Hint

   Consider the definition of irrotational flow.

5. 5.

   Consider two infinite parallel plates with one moving at a constant speed. Without using detailed equations, qualitatively describe how the velocity gradient changes as you move away from the moving plate towards the fixed plate.

   Hint

   Think about how fluid layers interact at a boundary.

6. 6.

   Assume a viscous fluid flowing between two plates is subject to a pressure gradient. How would the velocity profile differ in this case compared to a purely moving plate scenario? Explain the reasoning behind your answer.

   Hint

   Reflect on how pressure influences fluid dynamics.
