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.

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 ...

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 ...

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 ...

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 ...

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 ...

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.

The dappled starlight and swirling clouds of Vincent van Gogh’s “The Starry Night” are thought to reflect the artist’s tumultuous state of mind when he painted the work in 1889. Now, a new analysis by ...
