Numerical study of the square-root conformation tensor formulation for confined and free-surface viscoelastic fluid flows
(2016-12-01)
We present a numerical study of a stabilization method for computing confined and free-surface flows of highly elastic viscoelastic fluids. In this approach, the constitutive equation based on the conformation tensor, which ...
Development and application of wire-mesh sensors for high-speed multiphase flow imaging
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2015-08-14)
Multiphase flows are present not only in nature but also are very common in industrial activities such as in exploration, production and transport of oil and gas. In oil production, the mixture of gas, oil and water is ...
Spatial evolution of turbulence characteristics in weak hydraulic jumps
(TAYLOR & FRANCIS LTD, 2011)
This experimental investigation focuses on the turbulence features of weak hydraulic jumps in rectangular channels for two different approach flow lengths. The turbulent kinetic energy equation includes the turbulence ...
Laminar elliptic flow in the entrance region of tubes

New prediction methods for CO2 evaporation inside tubes: Part I - A two-phase flow pattern map and a flow pattern based phenomenological model for two-phase flow frictional pressure drops
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
An updated flow pattern map was developed for CO2 on the basis of the previous Cheng-Ribatski-Wojtan-Thome CO2 flow pattern map [1,2] to extend the flow pattern map to a wider range of conditions. A new annular flow to ...
Continuous flow injection reaction/stopped flow detection using derivative spectrophotometry. Determination of cobalt and iron in mixtures
(MARCEL DEKKER INC, 1996)
A continuous flow injection reaction-stopped flow detection method using derivative spectrophotometry was developed for the determination of cobalt and iron in mixtures. A conventional two-channel flow injection manifold ...
