Microperforated plate (MPP) absorbers are perforated plates with holes typically in the
submillimeter range and perforation ratios around 1%. The values are typical for …

Mechanisms for the formation of bead defects, such as humping, gouging, rippling, and
other unexpected surface patterns, encountered in welding or drilling are interpreted and …

Innovations in fluid mechanics have been leading to better food since ancient history, while
creativity in cooking has inspired fundamental breakthroughs in science. This review …

We present the results of a combined theoretical and experimental investigation of the
influence of surface tension the acceleration due to gravity. The theory of viscous hydraulic …

We present the results of an experimental investigation of the striking flow structures that
may arise when a vertical jet of fluid impinges on a thin fluid layer overlying a horizontal …

We report a novel and spectacular instability of a fluid surface in a rotating system. In a flow
driven by rotating the bottom plate of a partially filled, stationary cylindrical container, the …

Since the discovery of crispations on a vibrating fluid layer, numerous types of patterns
formed on fluid surfaces have been revealed. Here we report the observation of polygonal …

We provide an experimental demonstration that the circular hydraulic jump represents a
hydrodynamic white hole or gravitational fountain (the time reverse of a black hole) by …

When a laminar inclined circular jet impinges on a horizontal surface, it forms a non-circular
hydraulic jump resulting from the non-axisymmetric flow. In this study, we develop an …

The vertical impact of a rectangular liquid jet was experimentally studied using a high-speed
camera. Fluorescent dyes and tracer particles are used to visualize the thickness and …
