Turbulence: Where do we stand?

Turbulence is dramatic, beautiful and potentially dangerous. It happens in liquids as well as gases — think of breaking waves and raging rivers, or air streaming around a car or plane. By its very nature, turbulence is incredibly hard to describe. At the same time, a proper understanding of turbulence would have applications ranging widely across the mathematical, physical and engineering sciences.

That's why the Isaac Newton Institute for Mathematical Sciences is gearing up for a research programme, called Mathematical aspects of turbulence: Where do we stand?, to be held next year. In the meantime, we bring you some brief introductions to the basic notions of the maths of turbulence and fluid flows. Come along for the ride, we promise it won't be too bumpy!

Maths in a Minute: Fluid dynamics and the Euler equations — How does water, or indeed any fluid, move? The Euler equations let us look beneath the surface and mark the beginning of modern fluid dynamics.

Maths in a minute: The Navier-Stokes equations — A step up from the Euler equations are the Navier-Stokes equations. They are more general, but also present a huge challenge that could win you 1 million dollars. Find out more in this article from our library.

Maths in a minute: Computational fluid dynamics — The Navier-Stokes equations can be incredibly hard to solve, so how do you apply them in the real world? Computational fluid dynamics has the answer.

Maths in a minute: Turbulence and the Reynolds number — How does a steady and smooth flow suddenly turn turbulent? The Reynolds number helps to describe the transition.

Maths in a minute: Differential equations — All the equations mentioned so far are differential equations. If you don't know what those are, here's an introduction. Find out more in this article from our library.
