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 ...

An abrupt transition to turbulence occurs in a large variety of situations, ranging from the formation of spiral galaxies, to the fluid motion in the atmosphere and oceans, to flows over aeroplane ...
