Assessment of gas-particle flow models for pseudo-2D fluidized bed applications
(Taylor & Francis, 2018-04)
The aim of this work is to provide more insight into the general modeling criteria for simulating pseudo-2D bubbling fluidized beds. For this purpose, two experimental-based problems are studied. First, a fluidized bed ...
Análise numérica da dinâmica de crescimento da bolha de vapor em ebulição
(Universidade Estadual Paulista (Unesp), 2020-06-25)
O presente trabalho possui enfoque em apresentar e desenvolver um programa capaz de simular a dinâmica de crescimento de uma bolha em regime de ebulição nucleada. Apresenta também fundamentos de mecânica dos fluidos, ...
Flotation of high-grade fluorite in a short column under negative bias regime
(Minerals Engineering, 2006)
This paper presents flotation results carried out on fluorite ore using a relatively short column, operated under negative bias regime and without wash water. The term short column is used from a kinetic point of view from ...
Scaling of bubbling fluidized bed reactors
(Universidad Nacional de ColombiaMedellín - Minas - Doctorado en Ingeniería - Sistemas EnergéticosDepartamento de Procesos y EnergíaFacultad de MinasMedellínUniversidad Nacional de Colombia - Sede Medellín, 2020-12)
Esta tesis presenta un modelo matemático novedoso para la activación de carbón con CO2, vapor y una mezcla de CO2 / vapor. La principal contribución de este modelo es que el CO2 y el vapor reaccionan con distintos sitios ...

Análisis de procesos explosivos en el precio de los activos financieros: evidencia alrededor del mundo
(Universidad Católica de Colombia. Facultad de Ciencias Económicas y Administrativas, 2016-01)
This article analyzes different international share price indices for the period 1995-2013, in order to test for the existence and date of appearance of asset price explosions in the world’s stock markets. A sign test is ...
Experimental and numerical investigation of gas-liquid flows in the presence of Taylor and dispersed bubbles
(2020)
Escoamentos multifásicos desempenham um papel importante em processos industriais, especialmente na indústria química e de petróleo. Escoamentos desse tipo podem ocorrer em linhas horizontais, verticais e inclinadas, ...
Machine Learning for Financial Prediction Under Regime Change Using Technical Analysis: A Systematic Review
Recent crises, recessions and bubbles have stressed the non-stationary nature and the presence of drastic structural changes in the financial domain. The most recent literature suggests the use of conventional machine ...
