where ε is the average rate of dissipation of turbulence kinetic energy per unit mass, and; ν is the kinematic viscosity of the fluid.; Typical values of the Kolmogorov length scale, for atmospheric motion in which the large eddies have length scales on the order of kilometers, range from 0.1 to 10 millimeters; for smaller flows such as in laboratory systems, η may be much smaller.
Jackson and Eklund created two scales that have been proven to be psychometrically valid and reliable: the flow state scale-2 (which measures flow as a state), and the dispositional flow scale-2 (designed to measure flow as either a general trait or domain-specific trait).
The Taylor microscale is the intermediate length scale at which fluid viscosity significantly affects the dynamics of turbulent eddies in the flow. This length scale is traditionally applied to turbulent flow which can be characterized by a Kolmogorov spectrum of velocity fluctuations. In such a flow, length scales which are larger than the ...
Scaling of Navier–Stokes equation refers to the process of selecting the proper spatial scales – for a certain type of flow – to be used in the non-dimensionalization of the equation. Since the resulting equations need to be dimensionless, a suitable combination of parameters and constants of the equations and flow (domain ...
Fifteen pairs of items are repeated twice for the consistency scale. Achievement : A need to accomplish tasks well; Deference: A need to conform to customs and defer to others; Order: A need to plan well and be organized; Exhibition: A need to be the center of attention in a group; Autonomy: A need to be free of responsibilities and obligations
A Jackson-Pratt drain (also called a JP drain) is a closed-suction medical device that is commonly used as a post-operative drain for collecting bodily fluids from surgical sites. The device consists of an internal drain connected to a grenade-shaped bulb or circular cylinder via plastic tubing.

Large eddy simulation of a turbulent gas velocity field.. Large eddy simulation (LES) is a mathematical model for turbulence used in computational fluid dynamics.It was initially proposed in 1963 by Joseph Smagorinsky to simulate atmospheric air currents, [1] and first explored by Deardorff (1970).
