In a research project that has real implications for their regular laboratory work, a pair of physicists at Brown University ...

Modeling the behavior of liquids is important for a wide range of applications, from industrial processes and medical devices to computer graphics and visual simulations. However, despite many years ...

Traditional viscometers rely on capillary flow, and falling balls are simple and effective means for measuring fluid viscosity over a large range. However, their low measurement throughput and lack of ...

Rheology, high-speed imaging, and velocimetry combined to characterize how some roller-based nozzles perform so well with non-Newtonian fluids, such as whey protein.

Honey is already a pretty thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs ...

Conventional wisdom holds that an electric current never returns to its source nor follows a circular path. Instead, it flows from one electrode to another following a local electric field, obeying ...

Researchers have investigated the fluid dynamics of Helicobacter pylori (H. pylori) moving through gastric mucus using a 3D model and a magnetic field. H. pylori uses its corkscrew-like tail to move ...

When two fluids don't mix well, they sometimes form strange patterns called "viscous fingering," or Saffman-Taylor instability. Studying these patterns can help scientists understand how to design ...
