Question

The two plate in Couette flow are kept at the same temperature.

(a) True

(b) False

I had been asked this question in a job interview.

I would like to ask this question from Couette Flow topic in portion Numerical Techniques for Nonlinear Supersonic Flow, Elements of Hypersonic Flow, Couette and Poiseuille Flow of Aerodynamics

Answer 1

Correct answer is (b) False

Best explanation: To model the Couette flow, the two flat plates are kept at different temperatures. This causes a temperature gradient in the flow. This leads to the transfer of heat energy through the fluid. The heat transfer on the upper and lower plates are given by \(\dot {q}_e\) and \(\dot {q}_w\) respectively.
