Turbulence in Plant CanopiesAnnual Review of Fluid Mechanics - Tập 32 Số 1 - Trang 519-571 - 2000
John Finnigan
▪ Abstract The single-point statistics of turbulence in the ‘roughness sub-layer’ occupied by the plant canopy and the air layer just above it differ significantly from those in the surface layer. The mean velocity profile is inflected, second moments are strongly inhomogeneous with height, skewnesses are large, and second-moment budgets are far from local equilibrium. Velocity moments s...... hiện toàn bộ
Scale-Invariance and Turbulence Models for Large-Eddy SimulationAnnual Review of Fluid Mechanics - Tập 32 Số 1 - Trang 1-32 - 2000
Charles Meneveau, Joseph Katz
▪ Abstract Relationships between small and large scales of motion in turbulent flows are of much interest in large-eddy simulation of turbulence, in which small scales are not explicitly resolved and must be modeled. This paper reviews models that are based on scale-invariance properties of high-Reynolds-number turbulence in the inertial range. The review starts with the Smagorinsky model...... hiện toàn bộ
Fluid Mechanics in the Driven CavityAnnual Review of Fluid Mechanics - Tập 32 Số 1 - Trang 93-136 - 2000
PN Shankar, M. D. Deshpande
▪ Abstract This review pertains to the body of work dealing with internal recirculating flows generated by the motion of one or more of the containing walls. These flows are not only technologically important, they are of great scientific interest because they display almost all fluid mechanical phenomena in the simplest of geometrical settings. Thus corner eddies, longitudinal vortices,...... hiện toàn bộ
