Statistical method to calculate local interfacial variables in two-phase bubbly flows using intrusive crossing probes
(Pergamon-elsevier Science LtdOxfordInglaterra, 2000)
The phase distribution of upward co-current bubbly flows in a vertical square channel
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2004)
Structuring bubbles and foams in gelatine solutions within a circular microchannel device
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
A flow-focusing device with circular cross-section to produce monodispersed air bubbles and foams in several gelatine solutions is presented. Four flow regimes were studied by varying the gas pressure: dripping, bi-disperse ...
Visualization of the flow arund a bubble moving in a low viscosity liquid
(Revista Mexicana de Física, 2009)
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 comparative assessment of empirical and lattice Boltzmann method-based drag models for simulation of gas–solid flow hydrodynamics in a bubbling fluidized bed
(2017-08-01)
In simulations of fluidized beds using computational fluid dynamics (CFD), the description of gas–solid flow hydrodynamics relies on a drag model to account for the momentum transfer between gas and solid phases. Although ...
Experimental investigation of wall nucleation characteristics in flow boiling
(American Society of Mechanical Engineers, 2015-05)
Wall nucleation experiments have been performed in a vertical annulus test section for investigation of the bubble departure diameter and bubble departure frequency. The experimental data in forced convective subcooled ...
Evaluation of flow patterns and elongated bubble characteristics during the flow boiling of halocarbon refrigerants in a micro-scale channel
(ELSEVIER SCIENCE INC, 2010)
In the present study, quasi-diabatic two-phase flow pattern visualizations and measurements of elongated bubble velocity, frequency and length were performed. The tests were run for R134a and R245fa evaporating in a stainless ...
The effect of compressibility on the primary global instability of unforced laminar separation bubbles
(2019-12-01)
Laminar separation bubbles present a three-dimensional self-excited instability mechanism which leads to the appearance of spanwise-periodic structures. In incompressible flow, this mechanism was found to become active at ...
A non-intrusive probe for bubble profile and velocity measurement in horizontal slug flows
