Espectros de turbulência em terreno complexo
(Universidade Federal de Santa Maria, 2008-08-20)
Throughout this paper a spectral analysis is conducted on the superficial limit layer in complex terrains. The data used were collected in the central part of the state of Rio Grande
do Sul, in the Valley of Jacuí River. ...
Modelo espectral de heisenberg aplicado ao decaímento da turbulência na camada residual
(Universidade Federal de Santa Maria, 2005-10-22)
In the study of the dispersion of contaminants in the atmosphere by computational simulations, the Eulerian approach, based in the diffusionadvection equation, is largely employed. In these simulations, concentration values ...
Caos na camada limite atmosférica noturna
(Universidade Federal de Santa Maria, 2009-04-08)
A three-equation model, based on prognostic expressions for the Richardson number, turbulent kinetic energy and wind shear is proposed to represent turbulent behavior in the nocturnal boundary layer (NBL). Integration ...
A hipótese de turbulência localmente isotrópica e a universalidade da constante de Kolmogorov
(Universidade Federal de Santa Maria, 2006-05-03)
According to the Kolmogorov's fully developed turbulence theory established in 1941, there is an equilibrium range in which phenomenological quantities associated to the turbulence flow are described by laws of universal ...
