CFD and Aerodynamics Analysis of a Blown Wing using Stallion 3D

This guide condenses the video transcript into a short, actionable tutorial. Follow the steps below to replicate the workflow shown in the video.

Tutorial Steps (from Transcript)

1. Hello and welcome to Hanley Innovations. Today we will outline how to set up actuator discs in Stallion 3D to implement a blown wing concept.
2. First, we create the wing in Stallion 3D using the built-in geometry tools. This wing has a span dimension of 4 m and a cord of 1 meter.
3. It uses a NACA 4412 from the built-in library. Next, we enter the actuator discs parameters.
4. For all four, we set a force of 500 Newtons. We copy the first disc and set the Y center to minus 0.75.
5. Next, with the same copy, paste a discs with Y centers of 0.25 and minus0.25 respectively to complete the propulsion distribution. Next, set up the CFD using 1 million cubes with the initial X, Y, and Z settings of 2, 2 and two.
6. Use the default Navier Stokes solver. Then click the generate grid solve flow menu.
7. Stallion 3D will automatically generate the grid and solve the flow. The results show the effects of the disc's prop wash over the wing and in the wake.
8. We can now compare the lift force of the unpowered wing to that of the blown wing. The unpowered wing has a lift force of 24 lb in the 20 m/s flow field.
9. The blown wing has a lift of 70.8 lb. 
10. Until next time, thanks for watching.
