1. Desenvolvimento e calibração de um tanque de reaeração equipado com grade oscilante / Development and calibration of a reaeration tank equipped with oscillating grids
Este trabalho apresenta a calibração e o desenvolvimento de um tanque de reaeração, equipamento que gera turbulência com intensidade controlável por meio de grade oscilante. Foram realizadas adequações ao projeto inicial de construção do tanque, idealizado por ROMA, onde se buscou o equilíbrio e as limitações de funcionamento para que, em futuro

2. Experiments and theory for two grids turbulence
Turbulence generated by a pair of oscillating grids in a water tank is investigated using the digital particle image velocimetry technique. Vertical and horizontal components of fluctuating velocities are measured. Experimental profiles of the turbulent kinetic energy k, and the energy dissipation rate, xi, obtained from the fluctuating velocities, are prese

3. Fluxo de massa na interface ar-água em tanques de grades oscilantes e detalhes de escoamentos turbulentos isotrópicos / Gas transfer near the air-water interface in an oscillating-grid tanks and properties of isotropic turbulent flows
Gas transfer across the air-water interface in turbulent flows is an important process for many environmental systems. To improve the understanding of the basic principles involved in this phenomenon it is necessary to use suitable apparatus and experimental techniques. In this study, experiments and numerical simulation were conducted in a tank with one and

4. Estudo da estrutura turbulenta em escoamentos gerados por grades oscilantes / Study of the turbulence structure in drainage caused by oscillating grids
This work presents the project and construction of a tank with an oscillating grid, equipment which provides for the experimental studies of turbulence and its relation to mixing processes and gas transfer across fluid interface. Experiments were carried out with the use of digital particle image velocimetry technique, to investigate the properties of the pr
