How to prevent the flushing-induced plume without changing people's daily habits? Enlightened by thoughts of redesigning the restroom, this article provides a redesigned toilet using liquid-curtain-based strategy and verifies its advantages from the computational fluid dynamics. Two favorable effects are spotted: (1) the liquid curtain can suppress the upward virus particles (only 1% viruses can be lifted out of the toilet) and (2) the flow distribution caused by the liquid curtain can deliver virus particles into the sewage efficiently.
如何在不改变人们日常习惯的情况下防止冲水产生的羽流？受重新设计卫生间想法的启发，本文提出了一种基于液幕策略的重新设计的马桶，并通过计算流体动力学验证了其优势。发现了两个有利效果：（1）液幕可以抑制病毒颗粒向上扩散（只有1%的病毒能被带出马桶），（2）液幕引起的水流分布可以将病毒颗粒有效地输送到污水中。
