Certain kinds of motor oils behave differently. Ideally, an engineer would prefer the oil viscosity to remain the same when the engine is hot as when it is cold. Motor oil includes additives developed ...

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 ...

Researchers at Toyohashi University of Technology in Japan, in collaboration with the Institute of Translational Medicine and Biomedical Engineering (IMTIB) in Argentina and the Indian Institute of ...

The term “Nanofluids” was first proposed by Choi of Argonne National Laboratory USA in 1995, which meant nanoparticle fluid suspensions. After which, this interdisciplinary field has developed ...

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 ...

An international team of scientists has discovered how cancer cells exposed to high viscosity environments change the way they move to improve their invasiveness and favor metastases. The studies ...

New research findings show how higher viscosity, or resistance to flow, of the extracellular fluid that surrounds cells enables cancer cells to migrate more rapidly from a primary tumor to other sites ...
