A complete model for oxidation air-lift reactors
(Pergamon-elsevier Science LtdOxfordInglaterra, 2001)
Night irrigation reduction for water saving in medium-sized systems
(2003-04)
In many medium-sized irrigation systems water is wasted during the night because demand is low and supply is not reduced accordingly. A hydrodynamic model was applied, using MIKE 11 as a software tool, to simulate abrupt ...
Escoamento laminar em dutos de setor circular
(2015-07-01)
The fluid flow inside ducts is of great importance in engineering, because it is present in most domestic, commercial, and industrial application equipments. In this work was presented a hybrid analytical-numerical solution ...
Hydrodynamic aspects in anaerobic fluidized bed reactor modeling
(Elsevier Science Sa, 2008-12)
The main purpose of this paper is to analyze the adequacy of some hypotheses assumed in the literature for modeling mass transfer phenomena and hydrodynamics in bioreactors. Four different hydrodynamic models were investigated ...
Nonlinear delayed feedback model for incompressible open cavity flow
(American Physical Society, 2020-02)
The dynamics of an oscillating shear layer when confined is enriched by retarded actions whose physical modeling is not trivial. We present a nonlinear delayed saturation feedback model, which allows us to correctly reproduce ...
Effect Of Different Gas-solid Drag Models In A High-flux Circulating Fluidized Bed Riser
(AIDIC SERVIZI SRLMILANO, 2015)
Caracterização experimental da evolução do escoamento líquido-gás em golfadas em uma tubulação vertical
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-08-31)
Two-phase gas-liquid flow can assume different geometric configurations called flow patterns, one of these is the slug flow, characterized by the intermittency of a structure known as unit cell, which is composed by the ...
Impact of a rocky outcrop on hydrodynamics and geomorphology in a mesotidal channel
(Academic Press Ltd - Elsevier Science Ltd, 2019-09-30)
The purpose of the present work is to study the effect of an isolated depression and a related rocky outcrop on the flow field in a mesotidal channel of the Bahía Blanca Estuary, Argentina. To this end, measurements of ...
Bidirectional AC electroosmotic pumping by hydrodynamic channeling using 2D and 3D photoresist-derived carbon microelectrodes
In microfluidics, fluid movement is keystone for the correct operation of different system stages, including convective mixing, electrochemical sensing, and affinity bonding in immunoassays. Even though the most commonly ...
On the Rozovskii method to insolate secondary circulation from skewed flow
(2015-11-24)
Captured 2DV patterns of river flow velocities in a cross-plane provide the basis for inferring the existence of helical flow in open-channel bends and stream confluences. Researchers usually refer to the procedure named ...
