Question

4.2 Briefly explain how a thermal boundary layer differs from a velocity boundary layer. For the sake of argument, assume the temperature of the plate is higher than the freestream temperature.

4.3

a) Why do we have boundary layers?

b) Describe the nature of laminar flow. What physical parameters tell us we have turbulent flow?

c) What is the physical meaning of a Reynold%u2019s number (hint: think forces)

4.4

a) Explain the meaning of viscous dissipation.

b) Explain the physical meaning of each term in equation 4.6. Do not just describe the partial derivatives.

4.5 Explain the meaning of the Prandtl number.

4.5.2 How will we use the Nusselt number in convective heat transfer?

4.7.2 Explain the basic concepts of the Buckingham p Theorem.

4.7.5 Explain similarity in your own words.

4.10 Explain:

u:

u%u2019

4.11 Explain the Reynolds Analogy for turbulent flow over plane surfaces. How will we use it in heat transfer?

4.12 How do we treat a mixed boundary layer differently than a fully turbulent boundary layer in convective heat transfer?
