Effects of the intrinsic three-dimensionalization of laminar separation bubbles on the amplification of external disturbances
(2018-01-01)
The size and behavior of laminar separation bubbles is strongly related to the laminar-to-turbulent transition process that takes place downstream of the separation of the laminar boundary layer. Wind-tunnel experiments ...
A CFD study with analytical and experimental validation of laminar and turbulent mass-transfer in electrochemical reactors
(Electrochemical Society, 2018-01)
This work presents numerical simulations, with validation considering analytical expressions and experimental results, of masstransfer in electrochemical reactors under laminar and turbulent flows in ducts of rectangular ...
Enhancement of disturbance wave amplification due to the intrinsic three-dimensionalisation of laminar separation bubbles
(2019-10-01)
Previous studies demonstrated that laminar separation bubbles (LSBs) in the absence of external disturbances or forcing are intrinsically unstable with respect to a three-dimensional instability of centrifugal nature. This ...
Time-dependent mass-transfer behaviour under laminar and turbulent flow conditions in rotating electrodes: A CFD study with analytical and experimental validation
(Pergamon-Elsevier Science Ltd, 2019-07)
Results of numerical calculations and their comparison with analytical expressions or experimental data under laminar and turbulent flow conditions are reported. It is predicted the transient and steady-state behaviour of ...

Análise de estabilidade linear de escoamentos bidimensionais do Fluido Oldroyd-B
(Universidade Estadual Paulista (Unesp), 2016-06-27)
Diversos escoamentos de interesse prático são de fluidos viscoelásticos e muitas vezes é desejável saber se estes escoamentos propagam-se no estado laminar ou no turbulento. Embora a hidrodinâmica de fluidos viscoelásticos ...
Turbulent blood flow plays an essential localizing role in the development of atherosclerotic lesions in experimentally induced hypercholesterolaemia in rats
(BLACKWELL PUBLISHING, 2008)
Taking into account that atherosclerosis is a focal disease and high levels of plasma cholesterol are closely correlated with its pathogenesis, it is a challenge to explain how equal concentrations of cholesterol bathing ...
