Research into gas‐liquid flow dynamics in vertical pipelines has revealed that the interplay between the gas and liquid phases becomes considerably more complex when surfactants are introduced.

The study, published January 13 in Physical Review Letters, replaces the metal or plastic cogs of conventional gears with controlled flows of liquid. In their experiments, ...

We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, ...

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe needs to be equipped with a flap-type valve – which could fail. Now, however, scientists have created a new type ...
