Water/oil separation modeling by population balance equations - solution of the probability density function
(Instituto Balseiro - Centro Atómico BarilocheBariloche, 2014-09-23)
We discuss a model derived from the Williams population balance equations, written in mixture
form, to represent water-in-oil emulsions undergoing separation by gravity. The model includes
the treatment of the disperse ...
Population Balance Discretization for Growth, Attrition, Aggregation, Breakage and Nucleation
(Elsevier, 2015-08-28)
This paper presents a new discretization method to solve the population balance equation (PBE) for batch and unsteady/steady-state continuous perfectly-mixed systems. The numerical technique is valid for any size change ...
Comment on 'Analytical approach for solving population balances: A homotopy perturbation method' (2019) J. Phys. A: Math. Theor. 52385201
(IOP Publishing, 2020-09)
We analyse a recent application of homotopy perturbation method to some models for population balances. We show that the only result of the application of this implementation of the perturbation approach is the Taylor ...

Avaliação de modelos matemáticos para a simulação do escoamento água – ar na flotação por ar dissolvido utilizando fluidodinâmica computacional
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2018-02-21)
The concern with the future of water on the planet has increased in past years, mainly due to the recent water crisis suffered throughout the country. The dissolved air flotation (DAF) operation is an example of the ...

Método da quadratura de momentos aplicado à simulação da distribuição de tamanho de bolhas em um biorreator pneumático por CFD
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2023-02-24)
Aeration is crucial for the functioning of pneumatic bioreactors, as injecting gas into the system allows to perform agitation of the medium and as well as to improve mass transfer with lower energy consumption. Bubble ...
Protein-energy requirements of boys 12-14 y old determined by using the nitrogen-balance response to a mixed-protein diet
(American Society for Nutrition, 1992)
Short-term nitrogen-balance response to traded intakes of a vegetable mixed-protein diet and to a milk-egg protein diet was tested in eight healthy male children aged 12-14 y. They received 72, 104, 136, and 168 mg N · kg ...
