The risk of transmission of hepatitis C virus (HCV) infection is an important problem for the health care worker. HCV transmission by blood splashing into eyes is very rare. In a hemodialyses department, a 23-year-old female nurse splashed blood from a patient who was anti-HCV positive into her eyes. She washed her eyes with water immediately and reported to the infection control department. Sh...

A drop impacting a solid surface with sufficient velocity will splash and emit many small droplets. However, lowering the ambient air pressure suppresses splashing completely. This effect, robustly found for different liquid and substrate properties, raises the fundamental question of how air affects a spreading drop. In a combined experimental and numerical study we characterize the flow of ai...

We studied splashing on both smooth and rough dry surfaces using high speed photography. For smooth substrates, a striking phenomenon is observed: splashing can be completely suppressed by decreasing the pressure of the surrounding gas. The threshold pressure where a splash first occurs is measured as a function of the impact velocity and found to depend on the molecular weight of the gas and t...

Our goal is to realize sea surveillance systems in which an image processor detects intruding objects such as boats in the sea. A difficulty of the sea surveillance systems is to detect moving objects such as boats inhibiting false detection caused by flapping, splashing and shiny surface of the sea. Firstly we pick up factors of false detection in sea surveillance. Secondly we propose a new su...

In the field of fluid mechanics, many dynamical processes not only occur over a very short time interval but also require high spatial resolution for detailed observation, scenarios that make it challenging to observe with conventional imaging systems. One of these is the drop impact of liquids, which usually happens within one tenth of millisecond. To tackle this challenge, a fast imaging tech...

Breaststroke, butterfly, front crawl and back crawl: many of us learnt these swimming styles as kids while splashing around in our local pool. These strokes all involve the swimmer lying on their back or front, much like the way most fish swim. Of course, some people prefer to swim tilted to one side rather than face down even though the side-stroke evokes images of elderly swimmers in bathing ...

This paper considers the influence of hydrodynamic processes in movement free surface liquid partially filled tractor tanks. Splashing containers is a significant problem study functional stability marine, aerospace, rail, and automotive industries. After all, it affects productivity traffic safety. The same effect was observed when performing transportation work while delivering cargoes agricu...

During water droplet impact onto a dry or wet rough solid surface, several phenomena affect the surface erosion process, such as splashing, crown formation, and small emission to name few. These have been extensively studied for various simple target geometries. However, studies on complex irregular asymmetric topographies resulting from waterjet treatment never conducted. Furthermore, very lim...
