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 ...
Morphological evolution of oriented clay-containing block copolymer nanocomposites under elongational flow
(Pergamon-elsevier Science LtdOxfordInglaterra, 2013)
Vortex elongation in outer streaming flows
(Springer, 2020)
We study the secondary time-averaged flow (streaming) generated by an oscillating cylinder immersed within a fluid, under high amplitude forcing so that inertial effects are significant. This streaming is decomposed into ...
Computational Spinning Model to Study Different Expressions Proposed in the Literature for the Elongational Viscosity Evaluation from Spinning Experimental Data
(Asociación Argentina de Mecánica Computacional, 2006-12)
The relation between isothermal elongational flow and other flow kinematics, like shear flow, was of interest since the early stages of rheometry. The main seeking purpose was precisely to achieve the evaluation of the ...
Modelagem matemática do perfil da bolha alongada no escoamento bifásico em golfadas e análise de dados experimentais
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2017-11-23)
In the two-phase liquid-gas flow, the gas phase and the liquid phase are distributed in different geometries as a function of flow characteristics such as fluid flows rates, properties of each phase and geometric parameters ...
Elongational properties and crystallization of poly (isobutylene) melts probed by synchrotron radiation

Modeling the Melt Spinning of Polyethylene Terephthalate
(Sage Publications Ltd, 2000-04)
A model is formulated to describe quantitatively the melt spinning of a polyethylene terephthalate (PET) within the low range of take up velocities. The rheology of the polymer melt is described with the Phan-Thien and ...
Large scale structures in LES of an oscillating open channel flow under the influence of surface cooling
(Computers & Fluids, 2017-11)
Large-eddy simulation (LES) of open channel flow driven by an oscillating pressure gradient with zero surface shear stress was performed. The flow is representative of a tidal boundary layer in the coastal ocean under weak ...
