Determinação das células de convecção induzidas em tanques agitados por grades oscilantes

Turbulência
Abstract in Portuguese
A turbulência gerada em equipamentos de grade oscilante presta-se a uma série grande de comprovações experimentais de proposições teóricas. Isto ocorre tanto para a turbulência propriamente dita, como para os fenômenos de transporte a ela associados. Usualmente não se considera a presença de correntes preferenciais nas constatações experimentais conduzidas nesses equipamentos. Entretanto, para que as previsões teóricas possam ser definitivamente corroboradas, é preciso quantificar as correntes preferenciais e a sua forma, de modo que se possa inferir a sua influência nos fenômenos medidos. No presente estudo apresentam-se resultados da quantificação das correntes preferenciais em escoamentos gerados por grades oscilantes.

Turbulence
Abstract in English
Turbulence generated by oscillating grids is used in a series of experimental procedures to support or to test theoretical proposals. This way to conduct the studies is usual for turbulence itself and also for associated transport phenomena. Usually the preferential currents are not taken into account during the experiments conducted in oscillating grids equipments. However, to definitively corroborate theoretical predictions, it is necessary to quantify the preferential currents and to determine the shape of the flow, in a way that permits to infer the effects on the measured phenomena. In the present study, results related to preferential currents generated in a stirred grid equipment are presented.
