In Physics of Fluids, scientists describe their work on an at-home study of rheology, which is used to study the way non-Newtonian liquids or semisolid substances flow. The projects assigned to students had two parts: gathering qualitative visual evidence of rheological properties and taking quantitative measurements. The students checked for four behaviors – shear thinning viscosity, viscoelasticity, shear normal stress difference, and extensional viscosity – and even without access to laboratory rheometers, they developed creative and unique ways to carry out their measurements.

Why teapots always drip
The “teapot effect” has been threatening spotless white tablecloths for ages: if a liquid is poured out of a teapot too slowly, then the flow of liquid sometimes does not detach itself from the teapot, finding its way into the cup, but dribbles down at the outside of the teapot.
FAU Teams Up with Technion – Israel Institute of Technology on NSF Grant
FAU has received a $309,527 grant from the National Science Foundation to spearhead the project that will involve experimental work carried out at Technion, and numerical simulations and machine learning tasks conducted at FAU.

Aerosol modeling detects SARS-CoV-2 infectious dose, droplets
Fluid mechanics-based transport modeling in the human respiratory tract and research data were used to determine which droplet sizes are most like to reach the dominant infection site and the number of virus particles needed to trigger infection.
