Veryst modeled the trajectory of particles from an individual running at a moderate pace with another runner in their slipstream, while both are exhaling without wearing a mask.
Shear thickening and jamming in dense particulate suspensions can lead to undesirable processing inefficiencies and failure modes across a variety of product applications, including inkjet printer nozzles, medical autoinjectors, and porous filtration systems. In this case study, Veryst simulated the flow of a dense suspension through a syringe needle to evaluate the conditions that lead to shear jamming.
