The 'box cavity' paper seems more related to Coanda nozzles. I'm curious about the 45 and 60 angles cited and the shape of the outlets.

The tapered body paper looks to be of interest to the pickup truck aerocap builders.

The diffuser paper I will have to find time for later. :thumbup:

Edit: I'm halfway through the diffuser paper. Most interesting so far
  • Figure 2-2-2 which shows strategies for simulating a moving roadbed. The conclusion is that with a fixed roadbed you can compare but not quantify features.
  • Particle Image Velocimetry (PIV) measurements as shown in Figure 2-2-8, which uses laser light sheets and atomized olive oil to reveal and record flow within a field of view.
