Towards realistic simulations of human cough: effect of droplet emission duration and spread angle
Mogeng Li, Kai Leong Chong, Chong Shen Ng +6
Human respiratory events, such as coughing and sneezing, play an important role in the host-to-host airborne transmission of diseases. Thus, there has been a substantial effort in…
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,…
Convection-dominated dissolution for single and multiple immersed sessile droplets
Kai Leong Chong, Yanshen Li, Chong Shen Ng +2
We numerically investigate both single and multiple droplet dissolution with droplets consisting of lighter liquid dissolving in a denser host liquid. The significance of buoyancy…
Non-universal transport mechanisms in vertical natural convection with dispersed light droplets
Chong Shen Ng, Vamsi Spandan, Roberto Verzicco +1
We present results on the effect of dispersed droplets in vertical natural convection (VC) using direct numerical simulations based on a two-way fully coupled Euler-Lagrange approa…
