A formal description of the deflation process of a soap bubble attached to a cylindrical tube is provided, with emphasis on quantifying viscous and unsteady effects. Differing from prior studies, the proposed theoretical framework maintains its validity across a wide spectrum of parameter values that define the system. The model is validated through experimental results that can be reproduced at home using liquid soap and a straw, emphasizing its educational aspects.

Abstract
A formal description of the deflation process of a soap bubble attached to a cylindrical tube is provided, with emphasis on quantifying viscous and unsteady effects. Differing from prior studies, the proposed theoretical framework maintains its validity across a wide spectrum of parameter values that define the system. The model is validated through experimental results that can be reproduced at home using liquid soap and a straw, emphasizing its educational aspects.File in questo prodotto:
