astrophysical gyrokinetics: basic equations and linear theory
... gyrokinetic equations allow for a spatially varying mean magnetic field, temperature, and density. In an astrophysical plasma, the microinstabilities associated with the mean spatial gradients are unlikely to be as important as the MHD turbulence produced by violent large-scale events or instabiliti ...

P3.9 MEASURING THE VISCOUS DISSIPATION OF TURBULENT
... it averages velocities over a path of about 10 cm. This path-averaging implies that the smallest structures in the flow are not measured. Its calibration is robust, but one cannot use it to measure all terms of the turbulent kinetic energy budget. An anemometer often used in the laboratory is the ho ...

Liquid Flows in Microchannels
... where V 1 is the molar volume and NA is Avogadro’s number. For water, this spacing is 0.3 nm. In a 1 µm gap and a 50 µm diameter channel, the equivalent Knudsen numbers are 3 104 and 6 106 respectively, well within the range of obeying continuum flow. In gases, effects such as slip at the wall ...
