To simulate and analyze the effect of an expiratory event on a viscoelastic filament, an experimental bench was set up to stretch a sample of polymer solution and destabilize the BOAS structure formed, by a controlled air flow. The setup is fully automated, allowing statistical measurements on a large number of samples. The dynamics of the filament as well as the released drops are observed by multi-exposure and dual-wavelength inline digital holography. This method allows us to measure the size, position and velocity of the particles in a 3D volume.
The experiment presented here serves as a simple model for the atomization induced on a viscoelastic filament during a human expiratory event.
