Spin-affected reflexive and stretching separation of off-center droplet collision
Chengming He, Lianjie Yue, Peng Zhang
Recent studies have demonstrated the significant roles of droplet self-spin motion in affecting the head-on collision of binary droplets. In this paper, we present a computational…
Non-axisymmetric flow characteristics in Head-on Collision of Spinning Droplets
Chengming He, Peng Zhang
Effects of spinning motion on the bouncing and coalescence between a spinning droplet and a non-spinning droplet undergoing the head-on collision were numerically studied by using…
Unified Viscous-to-inertial Scaling in Liquid Droplet Coalescence
Xi Xia, Chengming He, Peng Zhang
This letter presents a theory on the coalescence of two spherical liquid droplets that are initially stationary. The evolution of the radius of a liquid neck formed upon coalescenc…
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…
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…
Vortex-Ring-Induced Internal Mixing Upon the Coalescence of Initially Stationary Droplets
Xi Xia, Chengming He, Dehai Yu +2
This study employs an improved volume of fluid method and adaptive mesh refinement algorithm to numerically investigate the internal jet-like mixing upon the coalescence of two ini…
