Problem 2

Problem

On your finest mesh (100x20), rerun the FLUENT calculation for Reynolds numbers 200 and 500 using the "second-order upwind" scheme. Note: change the Reynolds number by adjusting the molecular viscosity µ. Plot the centerline velocity and skin friction as a function of axial distance for Re = 100 (previous problem), 200, and 500. Plot all three cases on the same graph for comparsion. Briefly explain the trend you observe as the Reynolds number increases.

...

Your solution should look something like the plots below:
