I'm in the process of re-designing my velomobile. This new design will be the third iteration.
Are there any free tools that you are aware of that will aid in the design of the shell, which will give actual charts or numbers to work with and not just a graphical representation? I'm looking for something that tells me what the air is doing as it passes over the shape, whether the flow is laminar or turbulent, whether the boundary layer is attached, what the pressure is at various points in the shape, overall drag coefficient value, coefficient of downforce/life values, ect.
This video was a good basic primer, but the 6 actual steps listed to minimize drag, little was explained regarding exactly HOW it is done.
I don't have thousands of dollars for software or tens of thousands of dollars for wind tunnel testing, nor do I want to have to make multiple iterations of the same thing as that takes hundreds of hours of work each time just to get a chance to tuft test it.
