Viscous Dissipation, Helicity and Enstrophy of Bouncing Droplets undergoing Off-center Collision
Chengming He, Xi Xia, Peng Zhang
The off-center collision of binary bouncing droplets of equal size was studied numerically by a volume-of-fluid (VOF) method with two marker functions, which has been validated by…
Flickering of buoyant diffusion flames: a vortex dynamics revisit
Xi Xia, Peng Zhang
Previous studies have found that the flickering of buoyant diffusion flames is associated with the periodic shedding of a toroidal vortex, which is formed under gravity-induced she…
Vortex-dynamical Interpretation of Anti-phase and In-phase Flickering of Dual Buoyant Diffusion Flames
Tao Yang, Xi Xia, Peng Zhang
Anti-phase and in-phase flickering modes of dual buoyant diffusion flames were numerically investigated and theoretically analyzed in this study. Inspired by the flickering mechani…
Scalings in Coalescence of Liquid Droplets
Xi Xia, Chengming He, Peng Zhang
This letter presents a scaling theory of the coalescence of two viscous spherical droplets. An initial value problem was formulated and analytically solved for the evolution of the…
