Verification and Validation

Verification

One of the ways we can verify our data is by refining the mesh. Open up the mesh, and increase the Number of Divisions for Edge Sizing and Edge Sizing 2 to 100. Click Mesh in the Outline window, and in the Details window, expand statistics. The number of elements should now be 40000.

Exit out of the mesher, and click in the project schematic. Open up the solver, and solve the simulation using the same boundary conditions, solver, etc. Again, calculate the force coefficients and graph the pressure coefficient.

Validation

To validate our data, we will take a compare the data from actual experiment. Much thanks to David Caughey for providing us with the experimental data.

Below is a graph displaying the comparing Coefficient of Pressure along the airfoil for the experimental data and the CFD simulation.
