It is well established that the data reported for the daily number of infected cases during the first wave of the COVID-19 pandemic were inaccurate, primarily due to insufficient tracing across the populations. Due to the uncertainty of the...
Investigation of theoretical scaling laws using large eddy simulations for airborne spreading of viral contagion from sneezing and coughing [0.03%]
基于大涡模拟的喷嚏和咳嗽引起空气中病毒传播的理论尺度规律研究
K Liu,M Allahyari,J Salinas et al.
K Liu et al.
Using a set of large eddy point-particle simulations, we explore the fluid dynamics of an ejected puff resulting from a cough/sneeze. The ejection contains over 61 000 potentially virus-laden droplets at an injection Reynolds number of abou...
Effects of the filter microstructure and ambient air condition on the aerodynamic dispersion of sneezing droplets: A multiscale and multiphysics simulation study [0.03%]

This study investigates how airborne pollen pellets (or grains) can cause severe respiratory-related problems in humans. Given that pollen pellets can capture ribonucleic acid viruses, we show that airborne pollen grains could transport air...
Influence of spanwise flexibility on steady and dynamic responses of airfoils vs hydrofoils [0.03%]

The second and third waves of coronavirus disease-2019 (COVID-19) pandemic have hit the world. Even after more than a year, the economy is yet to return to a semblance of normality. The conference/meeting room is one of the critical section...
A computational study of expiratory particle transport and vortex dynamics during breathing with and without face masks [0.03%]
有和没有佩戴口罩情况下呼吸过程中飞沫传播及漩涡动力学的数值模拟研究
Ali Khosronejad,Seokkoo Kang,Fabian Wermelinger et al.
Ali Khosronejad et al.
We present high-fidelity numerical simulations of expiratory biosol transport during normal breathing under indoor, stagnant air conditions with and without a facile mask. We investigate mask efficacy to suppress the spread of saliva partic...
