Fluid dynamics is the branch of physics concerning fluid flow. It is distinguishable from other disciplines in fluid mechanics as it deals with fluids in motion. In physics, a fluid is a substance ...

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 ...

For most investigators the culture of mammalian cells has meant the use of traditional flasks or dishes. While this technique has proved useful for many studies, it is widely recognized that cells ...

To understand viscosity, laminar flow must be understood. This is when a gas or fluid flowing over a surface results in the molecules next to the surface having zero speed. As the distance from the ...

This question is often best answered by example. Imagine a styrofoam cup with a hole in the bottom. If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey ...

If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence of ...

High-viscosity fluids, on the other hand, behave quite differently. They flow slowly, resist deformation, and, in some cases, act more like solids than liquids, posing challenges when it comes to ...
