wind tunnel app: Algorizk (ios & android)
 

A friend of mine (whose dad made the streamlined aero model T in the 1930's) showed me a neat looking app on his ipod last week. The simulation looked really good.

There's a free and paid version, and I don't think you can place your own shape in the free version.

It probably won't run on my old Android, but if anyone tries it, let us know.

I just installed the free version. Its pretty neat, gives a nice visualization to what I imagine happens. Ran fine on my s3, but the phone did get a little warm.

Its main demonstration is an airfoil with smoke. You can adjust abgle of the airfoil and speed of the smoke. You can also view either smoke, pressure, or relative air speed around the shape.
