论文摘要
预测和对比，面罩，脖子步态和面罩的功效被预测和对比。特别是，颈门的晶格弹簧模型是晶格Boltzmann模拟的输入。晶格Boltzmann方法用于通过各种面部覆盖物捕获流体动力学。在该流场中模拟了呼吸液滴的蒸发和运输，并且不同面部覆盖物在停止呼吸液滴扩散时的疗效被阐明并形成对比。与最近的实验研究一致，我们预测颈试验器至少与布面膜一样有效，并且两者都优于面罩。
The efficacy of face masks, neck gaiters and face shields are predicted and contrasted. In particular, a Lattice Spring Model of a neck gaiter serves as the input to a Lattice Boltzmann simulation. The Lattice Boltzmann method is used to capture the fluid dynamics both through and around various face coverings. The evaporation and transport of respiratory droplets is simulated in this flow field, and the efficacy of the different face coverings at stopping the spread of respiratory droplets are elucidated and contrasted. In agreement with recent experimental studies, we predict that neck gaiters are at least as effective as cloth masks, and both are far superior to a face shield.
