Computer simulation of a vortex. Vorticity in a fluid such as a liquid or a gas is generated by internal friction or viscosity between adjacent particles or layers. The colour coding indicates the gradient of the velocity which expresses a variation of the magnitude of the velocity: the closer are the different coloured bands the steeper are the velocity changes | |
