Wouter Bos at the École Centrale de Lyon in France and his colleagues have now tracked a turbulent fluid's motion by picking one point and following it as the fluid tosses it about.

Using further 3 - D dynamo simulations, which model the generation of magnetic field by turbulent fluid motions, Driscoll looked more carefully at the expected changes in the magnetic field over this period.

These winds flow through a galaxy, and push material out of it, but their turbulent motions are such that part of the material can be re-captured by the gravitational pull of the galaxy itself.

While many basic aspects of physics can be included (conservation of mass, energy etc.), many need to be approximated for reasons of efficiency or resolutions (i.e. the equations of motion need estimates of sub-gridscale turbulent effects, radiative transfer codes approximate the line - by - line calculations using band averaging), and still others are only known empirically (the formula for how fast clouds turn to rain for instance).

«This (non-isothermal isentropic profile) indeed brings us to the broader framework discussed by Maxwell, in the sense that convective turbulent motions are now taken into account, albeit implicitly....
