Speculative bubbles and contagion: analysis of volatility's clusters during the DotCom bubble based on the dynamic conditional correlation model
(2016-05-16)
Reviewing the de nition and measurement of speculative bubbles in context of contagion, this paper analyses the DotCom bubble in American and European equity markets using the dynamic conditional correlation (DCC) model ...

On discriminating sizes of CFD generated bubbles with signal processing analysis
(Elsevier, 2015)
The aim of this research work is to propose a signal processing based technique to classify and estimate
bubble sizes. Bubbles are generated by computational fluid dynamics simulations. Local measuring points
for velocity ...
Single-Bubble Dynamics in a Dense Phase Fluidized Sand Bed Biomass Gasification Environment
(ACS Publications, 2020)
Biomass gasification in fluidized beds is a process of important commercial value. The simulation of these fluidized bed units strongly depends on establishing bubble dynamics in dense phase sand fluidized beds. In these ...

Dynamics of sonoluminescing bubbles within a liquid hammer device
(American Physical Society, 2009-01)
We studied the dynamics of a single sonoluminescing bubble (SBSL) in a liquid hammer device. In particular, we investigated the phosphoric acid–xenon system, in which pulses up to four orders of magnitude brighter than ...
Speculative bubbles and contagion: analysis of volatility’s clusters during the DotCom bubble based on the dynamic conditional correlation model
(2015-09-24)
Revendo a definição e determinação de bolhas especulativas no contexto de contágio, este estudo analisa a bolha do DotCom nos mercados acionistas americanos e europeus usando o modelo de correlação condicional dinâmica ...
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 ...
Predicting bubble size and bubble rate data in water and in froth flotation-like slurry from computational fluid dynamics (CFD) by applying deep neural networks (DNN)
(Pergamon-Elsevier, 2016)
Accurate characterization of two phase bubbly flows is crucial in many industrial processes such as fluidized reactors, ore froth flotation, etc. The bubble size determines the rate at which components present in the gas ...
