At some point, most people have found themselves holding a tilted carton of milk or bottle of cooking oil, patiently waiting for the last drops to drip out. Now, physicists at Brown University have ...

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 ...

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 ...

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 ...

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 ...

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 ...

SenGenuity claims its ViSmart high-shear extended range sensor is the first solid-state sensor available for viscosity measurements in thick and viscous fluids. The sensor comes equipped with a smart ...

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 ...
