For the fluctuations round the potential yet really fluctuations, and showing within the following incompressible process of equations: on any wall; at preliminary time, and are assumed identified. This contribution arose from dialogue with J. P. Guiraud on makes an attempt to push ahead our final co-signed paper (1986) and the most proposal is to place a stochastic constitution on fluctuations and to spot the massive eddies with part of the likelihood house.

Dust ion-acoustic (DIA) holes appear when warm ions follow a vortex ion distribution . 24 2 Vortex Filaments and Where to Find Them Fig. 8: Vortex filaments are common features of the solar atmosphere. Here we see several erupting out of the surface. These can be several times longer than the Earth. 4 Concluding Remarks In this chapter, we have seen how vortex filaments exist in many areas of physical reality. Indeed, anywhere where there is a fluidic-type structure whether it is water, air, liquid helium or dilute alkali atoms, Cooper pairs in superconductors, or ultra-hot plasmas, vortex filaments appear.
5 Statistical and Fluid Mechanics The field of fluid mechanics is traditionally concerned with deterministic equations that model the flow of fluids given boundary conditions. The properties of fluids, however, may only be describable in a statistical sense, while exact configuration, composition, momentum, and energy are only known probabilistically. The philosophy behind applying statistical mechanics to fluids is that it can capture the broad features of a system without needing to understand the details.
Negative temperature states turn out to be important in explaining the forma- Fig. 1: The point vortex gas is a gas of interacting filaments. 1 The Point Vortex Gas 45 Fig. 2: The Agulhas current, where the Indian Ocean meets the Atlantic, produces eddies as warm and cold water mix. The eddies can combine to form larger circulations, eventually forming hurricanes, possibly as a result of negative temperature states. Credit: NOAA tion of hurricanes. In the Atlantic many of these storms form as a result of eddies emerging from the Agulhas current (Fig.
