Three-dimensional simulations of the off-axis collisions of two drops are presented. The full Navier-Stokes equations are solved by a FrontTrackingFinite-Difference method that allows a fully deformable fluid interface and the inclusion of surface tension. The drops are accelerated towards each other by a body force that is turned off before the drops collide. Depending on whether the interface...

Background: Cataracts are the leading diseases that cause blindness. Cataracts can be treated with surgery. Pain, itching, burning, and a foreign body sensation in the eye are common ocular complaints of patients in recovery. In this study, we compared the effect of Ketorolac eye drops and naphazoline antazoline eye drops on reducing complaints of surgery. Methods: This randomized clinical tri...

The steady deformation and breakup of emulsion drops in a uniform electric field are considered experimentally. Due to the low volume fraction of inner drops, the emulsions can be effectively assumed as Newtonian fluids with spatial nonuniformity. The measurements of the electrical properties show that the oil-in-water (o/w) emulsion drop behaves like a conducting drop. On the other hand, the w...

In this paper, we examine spatio-temporal evolution of free moving drops in a vertically stratified fluid and study the role of stratification on the rise velocity of a single drop, two drops and a swarm of rising drops. Utilizing fully resolved three-dimensional Direct Numerical Simulations (DNS), we discuss the effects of density stratification on the interaction of two drops and microstructu...

The combination of anti-glaucoma eye drops is frequently used in clinical treatment, and it is known that the combination can cause corneal damage. Recently, an anti-glaucoma combination eye drops is developed, and the treatment by the combination eye drops is expected to enhance quality of life. However, effects of the combination eye drops on corneal epithelial cell damage have not been clari...
