Avaliação dos termos da equação de balanço de fluxo de energia cinética turbulenta
(Universidade Federal de Santa Maria, 2015-07-09)
In this paper we propose a balance equation for turbulent flux of turbulent kinetic energy (TKE) in the planetary boundary layer (PBL) and its terms are evaluated through data generated by a numerical simulation model. ...
Modelo para turbulência na camada limite atmosférica noturna utilizando equações prognósticas para a energia cinética turbulenta e fluxo de energia na forma de calor sensível
(Universidade Federal de Santa Maria, 2014-01-16)
The determination of the turbulent fluxes in very stable conditions is done, generally, through parametrizations. In this work the turbulent fluxes are estimated, by using a simplified model, through prognostic equations ...
Caracterização de turbulência completamente desenvolvida através de cumulantes e processos multiplicativos
(Universidade Federal de Santa Maria, 2010-01-12)
In this work we study drainings that present fully developed turbulence, that is, drainings characterized for raised Reynolds numbers. After a theoretical revision based on the model of Kolmogorov of 1941, we study the ...
Estudo sobre a turbulência na camada limite planetária
(Universidade Federal de Santa Maria, 2008-01-31)
In this research was made a study about the development of the boundary layer in Pedras Altas – RS. This study is made in two parts, fist a theoretician introduction then some datum, collected from a meteorological tower, ...
Estabilidade na camada limite atmosférica e intermitência nas pequenas escalas
(Universidade Federal de Santa Maria, 2008-12-18)
Although the understanding of turbulence is essential in many areas of science and technology, yet very little is known about its structure and its phenomenology. Since the first statistical models of decades of forty and ...
