An inaugural lecture by Professor Zhiyin Yang

Inaugural Lecture: Professor Zhiyin Yang

The understanding of turbulence is one of the most intriguing and important problems in physics and engineering. Most fluid flows are turbulent - from countless technological devices and household appliances of modern society to geophysical and astrophysical phenomena including planetary interiors, oceans and atmospheres and stellar physics and so on. Despite the widespread occurrence of fluid flow and the ubiquity of turbulence, the “problem of turbulence" remains to this day one of the unsolved problems of classical mathematical physics.

The problem of turbulence has been studied by many of the greatest physicists, mathematicians and engineers since the 19th century, and yet we do not understand in complete detail how or why turbulence occurs, nor can we predict turbulent behaviour accurately in many situations.

This lecture will give an overview of turbulence and demonstrate how numerical simulation can help to advance the understanding of turbulence and its occurrence.
