OBSERVATION of the flow pattern of a two-dimensional liquid jet directed into a blind cavity formed by solid surfaces indicates that the entire pattern may be treated as a fluidic oscillator circuit.

Driving force An experiment has confirmed that an oscillating temperature gradient boosts heat flow in fluids. (Courtesy: iStock/Mervana) Physicists in the Czech Republic have shown that heat flows ...

No-slip boundary condition is one of the common assumptions in rheological analysis, especially for polymer melt flow in capillary rheometers. In fluid dynamics, this assumption means that at the wall ...
