Diferentes técnicas de condicionamento em séries temporais turbulentas
(Universidade Federal de Santa Maria, 2005-12-09)
The dynamics process of the atmosphere near Earth ground is controled by two main forcings, termical and machanics. These process are reponsible for the atmospheric flow variability in this layer, and this variability ...
Comparação dos fluxos turbulentos em diferentes condições de estabilidade e topografia
(Universidade Federal de Santa Maria, 2004-05-04)
In this study sensible and latent heat fluxes as well as momentum flux were analysed in terms of similarity parameters. The intensity of the turbulence and the correlation functions are also studied. The data used in ...
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 ...
