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…
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,…
Data-driven identification of the spatio-temporal structure of turbulent flows by streaming Dynamic Mode Decomposition
Rui Yang, Xuan Zhang, Philipp Reiter +3
Streaming Dynamic Mode Decomposition (sDMD) (Hemati et al., Phys. Fluids 26(2014)) is a low-storage version of Dynamic Mode Decomposition (DMD) (Schmid, J. Fluid Mech. 656 (2010)),…
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…
