Fluids and Flows

The flow of liquids and gases is described by the Navier-Stokes equation

$$\rho\{{\partial u\over \partial t} + (u \cdot  \nabla) u \} = - \nabla p + \eta \nabla ^2u$$

This simple equation can describe how fluids move across a huge range of length scales, from ocean currents to swimming algae; from the drag behind racing cars to the raindrops on a spider’s web. Join us to explore the wonderful world of fluids and flows.
