MAE 3240/4230/5230: You DO NOT need to do this section. |
Exercise 1
Simulate the laminar boundary layer over a flat plate using FLUENT for a Reynolds number 
where
Change the value of the coefficient of viscosity µ from the tutorial example to get , keeping all other parameters the same. After changing the coefficient of viscosity rerun the solver for the mesh that was created in Step 3.
...
For example: if you wanted to make a square with a height and length of 1, your file would look like this:
| Zone | Point | X | Y | Z |
|---|---|---|---|---|
| 1 | 1 | 0 | 0 | 0 |
| 1 | 2 | 0 | 1 | 0 |
| 2 | 1 | 0 | 1 | 0 |
| 2 | 2 | 1 | 1 | 0 |
| 3 | 1 | 1 | 1 | 0 |
| 3 | 2 | 1 | 0 | 0 |
| 4 | 1 | 1 | 0 | 0 |
| 4 | 2 | 0 | 0 | 0 |
Flow outside of the boundary layer is inviscid and you will need to change this in your Model Setup.

What happens to the velocity at the outlet when we account for the displacement thickness? Compare your FLUENT results from this exercise to the results from the tutorial and the Blasius solution, what is happening to the velocity profile at the outlet?
