Question: Computer analysis of Prob. with to=f(x) and constant fluid properties: Calculate the flow, starting with inital conditions of flat velocity and temperature profiles at the inlet. Compare the computer results with the analytical results.
Problem: Starting with the constant-surface-temperature, thermal-entry-length solutions for a circular tube, calculate and compare the Nusselt numbers for constant surface temperature and for a linearly varying surface temperature, for very long tubes for a Reynolds number of 50,000 and a Prandtl number of 0.01. Repeat for a Prandtl number of 0.7 and discuss the reasons for the differences noted.
