Acoustic measurement of the bubble Sauter mean diameter d32
(Pergamon-Elsevier Science, 2016)
The importance of gas dispersion variables on the flotation process has led to the development of techniques that allow measuring and monitoring them in flotation. In the case of bubble size, the most used methods are based ...
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 ...
Applicability of a modified breakage and coalescence model based on the complete turbulence spectrum concept for CFD simulation of gas-liquid mass transfer in a stirred tank reactor
(Chemical Engineering ScienceAustralia, 2020-01-16)
A generalized model for bubble breakage and coalescence is proposed using Computational Fluid Dynamics – CFD for considering the complete energy spectrum. An eulerian model and balance equations are simultaneously used to ...

Secagem de suspensão de carbonato de cálcio em leito fluidizado utilizando análise espectral gaussiana
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia QuímicaEngenharia QuímicaUTFPR, 2017-05-29)
The phenomenon of partial or total defluidization of a fluidized bed is not desirable in industrial applications, as it may result in the interruption of the process. On the other hand, rapid detection of fluid dynamics ...
Avaliação experimental do coeficiente de transferência de calor suspensão-parede em regime de leito fluidizado borbulhante monitorado pelo método da frequência central gaussiana
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia MecânicaUTFPR, 2017-08-23)
Bubbling fluidized beds (BFBs) are well known as efficient systems for thermal energy transfer in several industrial applications. Although many works have already pointed out the performance features of gas-solid BFB heat ...
