The trade-offs necessary to choose a fluid involve a consideration of application requirements such as health, safety, and environmental effects, and fluid properties such as viscosity, stability, ...

A number of microorganisms have a talent for viscotaxis – movement through fluids to areas of thicker consistency (or higher viscosity). Now, Benno Liebchen and colleagues at the ...

It’s no secret that today’s iron is running at wider operating temperature ranges than ever for lubricants, and Tier 4 engines are heating up overall operation even more. As a result, more hydraulic ...

Fundamental constants: a minimum value of viscosity has been calculated by Kostya Trachenko and Vadim Brazhkin (Courtesy: iStock/3quarks). Viscosity is an everyday phenomenon recognizable in the ...

With an increase in temperature in a fluid, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. Viscosity typically decreases as temperature ...

With the magnificent real images of water pouring from the sky and the after-fire fumes from a car, there is no escaping from the laws of physics in movies either! Fluid simulation in the ’50s and ...
