“We found that sipping through a straw defies all the previously known laws for the resistance or friction of flow through a pipe or tube,” explains Leif Ristroph, an associate professor at New York ...

Rotameter flow meters are devices that can measure the flowrate of liquids and gases. Generally, the rotameter is a tube made of plastic, glass or metal combined with a float, which responds linearly ...

Whether it is oil gushing through pipelines or blood circulating through arteries, how liquids flow through tubes is perhaps the most fundamental problem in hydrodynamics. The challenge is to maximize ...

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes.

Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...

One milligram per hour: fluid flow can be measured with great precision using a tiny ‘wobbling’ tube with a diameter of only 40 micrometers. Thanks to a new technique, the sensor, which makes use of ...

This January, a group of researchers in Cornell’s Collective Embodied Intelligence Lab overcame a barrier in soft robotics by designing and modeling a system that takes advantage of fluid viscosity.

Interactions between molecules and electrons in carbon nanotube walls can cause 'quantum friction'. (Courtesy: Geoffrey Monet, ENS) When water moves through nano-sized channels made of carbon, its ...

Nanofluidic transistors, also known as nanofluidic systems or nanofluidic devices, are innovative tools that control the flow of fluids, such as water or ions, through nanoscale channels using ...
