Energy concentration and positional stability of sonoluminescent bubbles in sulfuric acid for different static pressures
(American Physical Society, 2013-09)
In this study we report several experimental and numerical results on the influence of static pressure (P0) over the main parameters in single bubble sonoluminescence (SBSL), using a sulfuric acid aqueous solution (SA) ...

Análise do escoamento água, óleo e gás em padrão disperso
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-07-02)
The effect of the insertion of a bubble swarm on the separation of finely dispersed oil droplets in a liquid flow was investigated experimentally and numerically. The generation of gas bubbles and oil droplets in a liquid ...
Green's function and infinite-time bubbling in the critical nonlinear heat equation
(European Mathematical Society, 2020)
Let Omega be a smooth bounded domain in R-n, n >= 5. We consider the classical semilinear heat equation at the critical Sobolev exponent.
ut =Delta u + un+2/n-2 in Omega x (0, infinity), u = 0 on partial derivative Omega ...
Influência da interação fluido-superfície sobre a dinâmica de nucleação de bolhas de vapor em cavidades artificiais
(Universidade Estadual Paulista (Unesp), 2021-08-06)
A constante procura por técnicas que otimizem o processo de transferência de calor, incluindo mudança de fase, torna necessária a compreensão da dinâmica da bolha de vapor no processo de ebulição. Dessa forma, o presente ...
Storm time equatorial plasma bubble zonal drift reversal due to disturbance Hall electric field over the Brazilian region
(American Geophysical Union, 2016-05-18)
The dynamics of equatorial ionospheric plasma bubbles over Brazilian sector during two magnetic storm events are investigated in this work. The observations were made at varying phases of magnetic disturbances when the ...
Investigação do fenômeno das bolhas em soldagem subaquática molhada com arame tubular auto protegido
(Universidade Federal de Minas GeraisBrasilPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2019-05-30)
The bubble formation mechanism of underwater wet flux cored arc welding (FCAW) is strongly
associated with variation in electrical signals and arc stability. Good understanding of bubble
formation mechanism can be helpful ...
