It is well established that droplets carrying infectious pathogens with diameters of 1\u20135\u2009\u03bcm remain suspended in the air for several hours and transported by the air currents over considerable distances (e.g., in meters). This study used a highly resolved mesh to capture the multiphase turbulent buoyant cloud with suspended droplets produced by a cough. The cough droplets' dispersion was subjected to thermal gradients and evaporation and allowed to disperse between two humans standing 2\u2009m apart. A nasal cavity anatomy was included inside the second human to determine the inhaled droplets. Three diameter ranges characterized the droplet cloud, &amp;lt;5\u2009\u03bcm, which made up 93% of all droplets by number; 5 to 100\u2009\u03bcm comprised 3%, and &amp;gt;100\u2009\u03bcm comprising 4%. The results demonstrated the temporal evolution of the cough event, where a jet is first formed, followed by a thermally driven puff cloud with the latter primarily composed of droplets under 5\u2009\u03bcm diameter, moving with a vortex string structure. After the initial cough, the data were interpolated onto a more coarse mesh to allow the simulation to cover ten minutes, equivalent to 150 breathing cycles. We observe that the critical diameter size susceptible to inhalation was 0.5\u2009\u03bcm, although most inhaled droplets after 10\u2009min by the second human were approximately 0.8\u2009\u03bcm. These observations offer insight into the risk of airborne transmission and numerical metrics for modeling and risk assessment.<\/jats:p>","DOI":"10.1063\/5.0072148","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T11:21:51Z","timestamp":1639567311000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":32,"title":["Large eddy simulation of cough jet dynamics, droplet transport, and inhalability over a ten minute exposure"],"prefix":"10.1063","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5443-761X","authenticated-orcid":false,"given":"Hadrien","family":"Calmet","sequence":"first","affiliation":[{"name":"Department of Computer Applications in Science and Engineering, Barcelona Supercomputing Center (BSC-CNS) 1 , Barcelona,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0476-0237","authenticated-orcid":false,"given":"Kiao","family":"Inthavong","sequence":"additional","affiliation":[{"name":"Mechanical & Automotive Engineering, School of Engineering, RMIT University 2 , Melbourne,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5267-204X","authenticated-orcid":false,"given":"Ambrus","family":"Both","sequence":"additional","affiliation":[{"name":"Department of Computer Applications in Science and Engineering, Barcelona Supercomputing Center (BSC-CNS) 1 , Barcelona,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7026-558X","authenticated-orcid":false,"given":"Anurag","family":"Surapaneni","sequence":"additional","affiliation":[{"name":"Department of Computer Applications in Science and Engineering, Barcelona Supercomputing Center (BSC-CNS) 1 , Barcelona,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9901-7942","authenticated-orcid":false,"given":"Daniel","family":"Mira","sequence":"additional","affiliation":[{"name":"Department of Computer Applications in Science and Engineering, Barcelona Supercomputing Center (BSC-CNS) 1 , Barcelona,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beatriz","family":"Egukitza","sequence":"additional","affiliation":[{"name":"Department of Computer Applications in Science and Engineering, Barcelona Supercomputing Center (BSC-CNS) 1 , Barcelona,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2592-1426","authenticated-orcid":false,"given":"Guillaume","family":"Houzeaux","sequence":"additional","affiliation":[{"name":"Department of Computer Applications in Science and Engineering, Barcelona Supercomputing Center (BSC-CNS) 1 , Barcelona,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"2025052817015090000_c1","doi-asserted-by":"publisher","first-page":"911","DOI":"10.4209\/aaqr.2020.04.0158","article-title":"A letter about the airborne transmission of SARS-CoV-2 based on the current evidence","volume":"20","year":"2020","journal-title":"Aerosol Air Qual.
