Reexamine the problem of laminar flow with heat generation. Now do the analysis for a constant heat flux at the walls. How should the dimensionless temperature \(\theta\) be defined here? How is the Brinkman problem defined for this case?

Does the problem have an asymptotic solution for large \(\zeta\) similar to Eq. (12.12)? If so, derive this result and find the value of the Nusselt number.

Show some numerical results and compare them with the asymptotic solution.
