This study presents observations of turbulence dynamics made during the low winds portion of the Coupled Boundary Layers and Air-Sea Transfer experiment (CBLAST-Low). Observations were made of turbulent fluxes, turbulent kinetic energy, and the length scales of flux-carrying and energy-containing eddies in the ocean surface boundary layer. A new technique was developed to separate wave and turbulent motions spectrally, using ideas for turbulence spectra that were developed in the study of the bottom boundary layer of the atmosphere. The observations of turbulent fluxes allowed the closing of heat and momentum budgets across the air-sea interface. The observations also show that flux-carrying eddies are similar in size to those expected in rigid-boundary turbulence, but that energy-containing eddies are smaller than those in rigid-boundary turbulence. This suggests that the relationship between turbulent kinetic energy, depth, and turbulent diffusivity are different in the ocean surface boundary layer than in rigid-boundary turbulence. The observations confirm previous speculation that surface wave breaking provides a surface source of turbulent kinetic energy that is transported to depth where it dissipates. A model that includes the effects of shear production, wave breaking and dissipation is able to reproduce the enhancement of turbulent kinetic energy near the wavy ocean surface. However, because of the different length scale relations in the ocean surface boundary layer, the empirical constants in the energy model are different from the values that are used to model rigid-boundary turbulence. The ocean surface boundary layer is observed to have small but finite temperature gradients that are related to the boundary fluxes of heat and momentum, as assumed by closure models. However, the turbulent diffusivity of heat in the surface boundary layer is larger than predicted by rigid-boundary closure models. Including the combined effects of wave breaking, stress, and buoyancy forcing allows a closure model to predict the turbulent diffusivity for heat in the ocean surface boundary layer.

Resumo: O desenvolvimento de modelos matemáticos que visam simular as características operacionais das máquinas rotativas é importante para representar uma variedade de fenômenos expressivos que se manifestam durante a operação, para tanto é necessário a modelagem dos componentes que caracterizam o comportamento dinâmico do sistema. Este trabalho tem por objetivo determinar os parâmetros físicos que integram os selos de fluxo de folga fixa e angular ao modelo global de sistemas rotativos. As rigidezes e os amortecimentos são obtidos através da solução de equações governantes para líquidos escoando em selos anulares pelo método clássico das perturbações de ordem máxima um e a solução da ordem zero permite demonstrar a variação da pressão e velocidade para as equações de ordem zero. Os resultados obtidos foram validados com os valores apresentados pela literatura. O resultado deste trabalho poderá ser aplicado na modelagem global de uma máquina rotativa, de modo a tornar a análise mais completa do conjunto girante
Abstract: The development of mathematical models designed to simulate operational characteristics is important to represent a wide variety of expressive phenomena that manifest during the operation, and therefore it is necessary the components modeling that characterize the system dynamic behavior. This study aims to determine the physical parameters that influence the flow seals to fixed angles and variables in the global rotating systems model. The stiffness and damping are obtained by solving the governing equations for fluid flowing in the annular seals using the classic perturbation method of maximal order one. The zero-order solution allows to demonstrate the pressure and speed variation to zero order. The results were validated with the similar tests reported in the literature. This work results are eligible to be applied to model a global rotating machine in order to make a more complete rotor analysis

Texte intégralExchanges of heat and momentum at the air-sea interface play a major role in the formation and the dynamics of water and air masses. In spite of decades of research, we still need to improve our knowledge of these exchanges, and more specifically our knowledge of turbulent fluxes, which are key variables in meteorological and climate models. In these models, sub-grid turbulent processes, thus turbulent fluxes also have to be modeled, which is mostly done with the Monin-Obukhov (1954, MOS hereafter) similarity theory. However, on the one hand, the use of a model implies that coefficients have to be adjusted. On the other hand, the model itself may require improvements. Unfortunately, obtaining flux estimates that have a good accuracy is a challenging effort, because of the intrusive effect of the platform, the limited accuracy the instruments, and because the instruments have their own sampling volume.Our study focuses on the estimation of turbulent fluxes at sea from measurements made with the new OCARINA platform (autonomous trimaran) during two campaigns : STRASSE 2012 and AMOP 2014. We analyze the characteristics of turbulence in the surface boundary layer, we estimate the turbulent fluxes by different methods, and compare the values of fluxes depending on environmental conditions, taking into account the sea state
