Influences of different forces on the bubble entrainment into a stationary Gaussian vortex

On the dynamics of vortex–droplet co-axial interaction: insights into droplet and vortex dynamics

“…For a Gaussian vortex Using (4.14 a – c ), an expression for the lift force is obtained. As suggested by Zhang & Ni (2013), the Basset history force is neglected in the present modelling, as it is second order compared with the other forces. After substituting (4.8)–(4.14) in (4.7), and then performing some algebraic manipulation, the governing equation is written as Equation (4.14 b , c ) is a governing equation for the leading-edge motion under the influence of various forces.…”

The jet characteristics of bubbles near mixed boundaries

“…In terms of numerical simulations, significant efforts have been made in recent years. [20][21][22][23][24][25][26] Wang 27 analyzed the motion of bubbles with a free surface near an inclined solid wall with the boundary element method (BEM), which provides a reference for studying the interaction between the bubble and mixed boundaries. However, this work assumed that the wall is semi-infinite, with no influence from a bottom surface.…”

Bubble–bubble interaction effects on dynamics of multiple bubbles in a vortical flow field

“…Numerical results were compared with the experimental study of Choi and Ceccio 14 who recorded the deformation of individual cavitation vortex bubble produced by a laser-initiated nuclei passing through a region of pressure reduction and recovery. Ni et al 15 and Zhang and Ni 16 used one-way coupled particle tracking method and the boundary element method to simulate the entire process of the motion of a bubble in a Gaussian line vortex field, including its release, capture, inception, deformation and splitting.…”
