Turbulent momentum diffusivity within a circular tube

International Journal of Heat and Mass Transfer, 1963
Abstract The paper presents an analysis of turbulent shear flow in which Nikuradse's experimental variation of eddy diffusivity across a circular tube is predicted accurately from an harmonic mixing length theory. The harmonic form of characteristic length used in the analysis is derived from a theoretical consideration of the turbulent eddy ...

The diffusion of momentum under various flow conditions

2001
Abstract In the previous chapter, we have seen how heat-or miscible tracers-are transported by diffusion. The flux of heat, or of tracer, is then proportional to the gradient of the quantity being transported (temperature or tracer concentration) and directed along this gradient.

Momentum space diffusion equations for chain molecules

The Journal of Chemical Physics, 1980
A Fokker–Planck equation is derived for the reorientational and torsional motion of a flexible butane molecule. The analysis starts with the Liouville operator for a chain molecule in a fluid and by projection operator techniques yields an equation of motion for the reduced distribution function of the Euler angles, torsion angles, and the molecule ...

Gradual Information Diffusion and Asset Price Momentum [PDF]

, 2010
Gradual information diffusion model predicts that as private information travels across the population, pricing accuracy would improve and asset prices would exhibit momentum as a result. In laboratory markets I investigate the market’s aggregation capacity in response to varying proportions of informed traders as a consequence of information diffusion.
