Interface motion and hydrodynamic shear of the liquid slosh during the insertion of syringes upon autoinjector (AI) activation may damage the protein drug molecules. We experimentally investigate the interfacial motion and hydrodynamic shear due to the acceleration and deceleration of syringes. No study to date...
Pharmaceutical industry focuses on developing prefilled syringe and autoinjector (AI) products by expanding features and capabilities. However, most of them might not be aware of an undesired phenomenon that may occur during drug solution injection called cavitation collapse. Cavitation is a phenomenon in which rapid...
The value of the flowing soap film as an experimental platform depends on its ability to approximate the two-dimensional Navier-Stokes equation. A variety of experimental techniques have been applied to characterize the soap film patterns, with the measured quantities being the thickness and the velocity...
Cavitation is ubiquitous in nature and engineering systems and governs processes from corrosion in propeller blades to drugs getting through the endothelial cells. Since the collapse of the cavitation bubble is so violent that it generates an intense shock wave and induces high shear stress...
Splashes are ubiquitous in nature and engineering and govern processes from diving, to ocean oxygenation. Yet to date, we do not understand when or why sometimes the splash seals, and other times does not. This work presents the first detailed analysis and physical understanding of...
