论文摘要
[删节]自然产生的人（例如呼吸，说话，打喷嚏和咳嗽产生的液滴）包括几种类型的细胞（例如，免疫系统的上皮细胞和细胞），生理电解质，粘液和唾液中包含的生理电解质和病毒）。从物理学的角度来看，为了应对已成为全球主要公共卫生问题的新型冠状病毒SARS-COV-2流行病，该流行病已成为全球主要的公共卫生问题。我们研究冠状病毒气溶胶是否可以远离附近的邻居，并随着狭窄的空间内形成的对流电流而获得空降。我们还提供了一个建议，可以帮助减慢病毒的传播。
[Abridged] Naturally produced droplets from humans (such as those produced by breathing, talking, sneezing, and coughing) include several types of cells (e.g., epithelial cells and cells of the immune system), physiological electrolytes contained in mucous and saliva (e.g. Na+, K+, Cl-), as well as, potentially, several infectious agents (e.g. bacteria, fungi, and viruses). In response to the novel coronavirus SARS-CoV-2 epidemic, which has become a major public health issue worldwide, we provide a concise overview of airborne germ transmission as seen from a physics perspective. We study whether coronavirus aerosols can travel far from the immediate neighborhood and get airborne with the convective currents developed within confined spaces. We also provide a recommendation that could help to slow down the spread of the virus.
