An experimental study examining the relationship between bubble shape and rise velocity

Experimental studies on the terminal velocity of air bubbles in water and glycerol aqueous solution

“…(8), Ishii and Chawla correlation [27], Eq. (13), and Turton and Levenspiel [30], Eq. (16), seem to have a good performance over the entire range of Eo.…”

“…In gas-liquid two-phase flows, bubble dynamics, especially the bubble shape and rising velocity, are key parameters that affect the behavior of the gas-liquid two-phase flow, such as void fraction, gas residence time and gas-liquid interface transferring properties. Substantial work, including theoretical [6][7][8][9][10], experimental [11][12][13][14][15][16] as well as numerical attempts [17][18][19][20], have been done to improve the understanding of bubble dynamics in their great diversity.…”

Experimental studies on the shape and motion of air bubbles in viscous liquids

“…(12). Then the undetermined coefficients (a, b, c), standard deviation, residual sum of squares, correlation coefficient are obtained by applying the least-square fitting with the experimental data, and the results are shown in Table 2.…”

“…It has guiding significance for in-depth study of bubble dynamics in gas-liquid two-phase flow to solve many engineering problems. Researches on the bubble dynamics have been conducted for decades, and many achievements have been accomplished by using theoretical analysis [4][5][6][7][8], experimental measurement [9][10][11][12][13][14] and numerical simulation [15][16][17][18][19][20], showing that the interactions between gas and liquid, i.e. viscous force, gravity, surface tension, and inertial force, mainly dominate the behavior of bubble dynamics.…”

A numerical Euler–Lagrange method for bubble tower CO2 dissolution modeling

“…Previous experimental results by Maldonado et al (2013) show a unique relationship between shape and rise velocity, independent of solute type or concentration. This work involves solving a multi-physics process, for which the interaction between bubbles/particle movement and fluid is preferably described as a two-or fourth-way coupling in a Lagrangian frame (Strömgren, 2010), in cases of bubble rise in non-disturbed liquid phases this force interaction plays an important role in the development of the flow lines around the bubble swarm.…”
