台式自由涡与强迫涡实验仪
Comparing the free vortex's hyperbolic surface with the forced vortex's paraboloid is a standard rotating flow exercise. The 245 mm clear cylinder takes 8–24 mm outlet orifices for free vortices, and tangential jets with a paddle produce forced vortices. A bridge with eight depth needles at fixed radii and a traversing Pitot tube record the profile.
