Include viscous work term
Web14. To derive an analytical solution for the thickness of the thermal boundary layer, Equation IVb.2.9, it was qualitatively argued that the net viscous work term is generally negligible compared with the more dominant terms. The goal of this problem is to quantify the above argument for fluids having low, medium, and high Prandtl numbers. http://web.mit.edu/16.unified/www/SPRING/fluids/Spring2008/LectureNotes/f12.pdf
