Turbulence is one of the great mysteries of modern science. It is also one of the most important, as most of the flows we're interested in are turbulent. In some applications, such as industrial ...

Going with the flow: does an extra term lead to a better model of turbulence? (Courtesy: iStock/Mumemories) Identifying universal laws within fluid mechanics is notoriously difficult. So it has come ...

Until now it had been assumed that, once a flow of a fluid has become turbulent, turbulence would persist. Researchers have now shown that this is not the case. In their experiments they managed to ...

A phenomenological model is proposed in this paper for simulating the effect of wall friction in turbulent pipe flows.The flow in this model is divided into two regions: wall region and core region.

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences The factors are summarized which control the transfer to an absorbing wall of diffusing substances conveyed ...

Aerodynamic optimisation is of paramount importance in improving the design of aircrafts, automobiles as well as turbomachinery to reduce energy consumption and improve energy production efficiency.

We've been using pipes for a long time, but still don't have a clear picture of how turbulence develops within them. A recent study presents a new method to experimentally determine when this shift ...
