Velocity Estimate from Schlieren Flow Visualization

563 views

Hi,

I recently came across a blog on schlieren visualization.

I replicated it with the following: Convex lens (130 mm dia and 350 mm focal length), LED light source (5 mm white LED) and smartphone camera (Moto G4 Plus).

Flow visualization of a hair dryer can be seen here.

Can anyone suggest how to estimate the velocity of the air flow?

Thank you
