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.<\/jats:p>","DOI":"10.1063\/5.0033836","type":"journal-article","created":{"date-parts":[[2020,11,23]],"date-time":"2020-11-23T14:07:17Z","timestamp":1606140437000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":12,"title":["Liquid-curtain-based strategy to restrain plume during flushing"],"prefix":"10.1063","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6412-9087","authenticated-orcid":false,"given":"Su-Chen","family":"Wu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meng-Yue","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5965-1356","authenticated-orcid":false,"given":"Ji-Xiang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7059-4092","authenticated-orcid":false,"given":"Shuhuai","family":"Yao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun-yun","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2020,11,23]]},"reference":[{"key":"2025052317511807000_c1","doi-asserted-by":"publisher","first-page":"1239","DOI":"10.1001\/jama.2020.2648","article-title":"Characteristics of and important lessons from the coronavirus disease 2019 (COVID-19) outbreak in China: Summary of a report of 72 314 cases from the Chinese center for disease control and prevention","volume":"323","year":"2020","journal-title":"JAMA"},{"key":"2025052317511807000_c2","doi-asserted-by":"publisher","first-page":"142090","DOI":"10.1016\/j.scitotenv.2020.142090","article-title":"The role of computational fluid dynamics tools on investigation of pathogen transmission: Prevention and control","volume":"746","year":"2020","journal-title":"Sci.
