Question 1

What defines the thermal boundary layer?

The region where temperature varies from the wall temperature to the bulk fluid temperature.
The region of constant temperature in a fluid.
The distance where fluid first contacts a surface.

💡 Hint: Consider where the temperature gradients occur in fluid mechanics.

Question 2

True or False: The thermal boundary layer is always thicker than the hydrodynamic boundary layer.

True
False

💡 Hint: Review how Prandtl number influences the layers.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a fluid with a Prandtl number of 0.5 flowing over a heated surface, describe how you would expect the thickness of the thermal boundary layer to compare with the hydrodynamic boundary layer. What implications does this have for heat transfer?

💡 Hint: Reflect on how Prandtl number affects thermal properties.

Challenge 2 Hard

Design an experiment to measure the thickness of the thermal boundary layer over a flat plate. Describe the setup, measurements required, and expected observations.

💡 Hint: Consider how to measure temperature effectively against the fluid flow.
