Bistability in radiatively heated melt ponds
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
Melting and solidification processes, intertwined with convective flows, play a fundamental role in geophysical contexts. One of these processes is the formation of melt ponds on g…
Circular objects do not melt the slowest in water
Rui Yang, Thijs van den Ham, Roberto Verzicco +2
We report on the melting dynamics of ice suspended in fresh water and subject to natural convective flows. Using direct numerical simulations we investigate the melt rate of ellips…
Shape effect on ice melting in flowing water
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
Iceberg melting is a critical factor for climate change, contributing to rising sea levels and climate change. However, the shape of an iceberg is an often neglected aspect of its…
Ice melting in salty water: layering and non-monotonic dependence on the mean salinity
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
The presence of salt in ocean water strongly affects the melt rate and the shape evolution of ice, both of utmost relevance in geophysical and ocean flow and thus for the climate.…
Turbulent Rayleigh-Bénard convection with bubbles attached to the plate
Hao-Ran Liu, Kai Leong Chong, Rui Yang +2
We numerically investigate turbulent Rayleigh-Bénard convection with gas bubbles attached to the hot plate, mimicking a core feature in electrolysis, catalysis, or boiling. The exi…
Heat transfer in turbulent Rayleigh-Bénard convection within two immiscible fluid layers
Hao-Ran Liu, Kai Leong Chong, Rui Yang +2
We numerically investigate turbulent Rayleigh-Bénard convection within two immiscible fluid layers, aiming to understand how the layer thickness and fluid properties affect the hea…
Optimal ventilation rate for effective displacement ventilation
Rui Yang, Chong Shen Ng, Kai Leong Chong +2
Indoor ventilation is essential for a healthy and comfortable living environment. A key issue is to discharge anthropogenic air contamination such as CO2 gas or, more seriously, ai…
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…
