Homogeneous quantum electrodynamic turbulence

Decay of homogeneous two-dimensional quantum turbulence

3D Homogeneous Turbulence

In this chapter we focus on what can be called the purest turbulence problem, as well as the classical one. It is in fact so pure that, strictly speaking, it cannot exist in nature, although experience shows that natural turbulence often has behavior remarkably close to the pure form. This is the case where rotational and gravitational forces are negligible (i.e., g = f = 0); b or c can be cons...

2D Homogeneous Turbulence

2D homogeneous turbulence is relevant to geophysical turbulence on large horizontal scales because of the thinness of Earth’s atmosphere and ocean (i.e., H/L 1) and Earth’s rotation (i.e., Ro 1) and stable stratification (i.e., Fr 1), both of which tend to suppress vertical flow and make the 2D horizontal velocity component dominant. A detailed explanation for this involves the theory for geost...

Streamlines in stationary homogeneous isotropic turbulence and fractal-generated turbulence

We compare streamline statistics in stationary homogeneous isotropic turbulence and in turbulence generated by a fractal square grid. We examine streamline segments characterised by the velocity difference u D and the distance l between extremum points. We find close agreement between the stationary homogeneous isotropic turbulence and the decay region of the fractal-generated turbulence as wel...
