An easy experiment is suggested to visualize the shape of a jet of hot air, coming from a hair dryer, which encounters obstacles along its path. Quite simply, owing to the heating produced on a flat surface, it is possible to acquire infrared thermal images of the jet. As a particular example, we observe the entrainment of air which is the basis of the Coanda effect.

Abstract
An easy experiment is suggested to visualize the shape of a jet of hot air, coming from a hair dryer, which encounters obstacles along its path. Quite simply, owing to the heating produced on a flat surface, it is possible to acquire infrared thermal images of the jet. As a particular example, we observe the entrainment of air which is the basis of the Coanda effect.File in questo prodotto:
