Universality in microdroplet nucleation during solvent exchange in Hele-Shaw like channels
Yanshen Li, Kai Leong Chong, Hanieh Bazyar +2
Micro and nanodroplets have many important applications such as in drug delivery, liquid-liquid extraction, nanomaterial synthesis and cosmetics. A commonly used method to generate…
Growth of respiratory droplets in cold and humid air
Chong Shen Ng, Kai Leong Chong, Rui Yang +3
The ambient conditions surrounding liquid droplets determine their growth or shrinkage. However, the precise fate of a liquid droplet expelled from a respiratory puff as dictated b…
Inverse centrifugal effect induced by collective motion of vortices in rotating turbulent convection
Shan-Shan Ding, Kai Leong Chong, Jun-Qiang Shi +4
When a fluid system is subject to strong rotation, centrifugal fluid motion is expected, i.e., denser (lighter) fluid moves outward (inward) from (toward) the axis of rotation. Her…
Extended lifetime of respiratory droplets in a turbulent vapour puff and its implications on airborne disease transmission
Kai Leong Chong, Chong Shen Ng, Naoki Hori +3
To quantify the fate of respiratory droplets under different ambient relative humidities, direct numerical simulations of a typical respiratory event are performed. We found that,…
Instabilities driven by diffusio-phoretic flow on catalytic surfaces
Yibo Chen, Kai Leong Chong, Luoqin Liu +2
We theoretically and numerically investigate the instabilities driven by diffusiophoretic flow, caused by a solutal concentration gradient along a reacting surface. The important c…
From Rayleigh-Bénard convection to porous-media convection: how porosity affects heat transfer and flow structure
Shuang Liu, Linfeng Jiang, Kai Leong Chong +6
We perform a numerical study of the heat transfer and flow structure of Rayleigh-Bénard (RB) convection in (in most cases regular) porous media, which are comprised of circular, so…
From zonal flow to convection rolls in Rayleigh-Bénard convection with free-slip plates
Qi Wang, Kai Leong Chong, Richard J. A. M. Stevens +2
Rayleigh-Bénard (RB) convection with free-slip plates and horizontally periodic boundary conditions is investigated using direct numerical simulations. Two configurations are consi…
Two-layer Thermally Driven Turbulence: Mechanisms for Interface Breakup
Hao-Ran Liu, Kai Leong Chong, Qi Wang +3
It is commonly accepted that the breakup criteria of drops or bubbles in turbulence is governed by surface tension and inertia. However, also {\it{buoyancy}} can play an important…
Periodically modulated thermal convection
Rui Yang, Kai Leong Chong, Qi Wang +3
Many natural and industrial turbulent flows are subjected to time-dependent boundary conditions. Despite being ubiquitous, the influence of temporal modulations (with frequency …
Café Latte: Spontaneous layer formation in laterally cooled double diffusive convection
K. L. Chong, R. Yang, Q. Wang +2
In the preparation of Café Latte, spectacular layer formation can occur between the expresso shot in a glass of milk and the milk itself. Xue et al. (Nat. Commun., vol. 8, 2017, pp…
Subcritical behaviour in double diffusive convection within the diffusive regime
Kai Leong Chong, Rui Yang, Yantao Yang +2
We conduct two- and three-dimensional simulations for double diffusive convection in the diffusive regime, where the fluid flow is driven by a destabilizing temperature gradient an…
