This lift-off is followed by a return to the ground or by a fly-away in the sense of continued departure from the ground. Related phenomena arise in the lift-off of an air vehicle from, effectively, moving ground. The present investigation seeks fairly precise mechanistic conditions under which lift-off and subsequent return or fly-away occur for a thin body or more generally for any thin gap of fluid between a body and the ground. Nonlinear fluid\u2013solid interaction takes place in which the motion of the body and the surrounding fluid affect each other. Small-time analysis on lift-off and a numerical study are presented, followed by large-time analysis showing a critical flow speed for fly-away for any shape of the body. The changes in ground effect, from being dominant during lift-off to diminishing in fly-away, are explored together with relevant applications.<\/jats:p>","DOI":"10.1098\/rspa.2018.0286","type":"journal-article","created":{"date-parts":[[2018,11,21]],"date-time":"2018-11-21T03:20:02Z","timestamp":1542770402000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Fluid flow lifting a body from a solid surface"],"prefix":"10.1098","volume":"474","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1125-3631","authenticated-orcid":true,"given":"Samire","family":"Balta","sequence":"first","affiliation":[{"name":"Department of Mathematics, University College London, London WC1E 6BT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4850-995X","authenticated-orcid":true,"given":"Frank T.","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University College London, London WC1E 6BT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2018,11,21]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-7091-6706-9_9"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.1029\/93JD00396"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00191019"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s003480050054"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022112064001173"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022112010005057"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.100.058001"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1158954"},{"key":"e_1_3_7_10_2","doi-asserted-by":"publisher","DOI":"10.1017\/jfm.2016.655"},{"key":"e_1_3_7_11_2","doi-asserted-by":"publisher","DOI":"10.1243\/09544062JMES1111"},{"key":"e_1_3_7_12_2","doi-asserted-by":"publisher","DOI":"10.1139\/tcsme-2009-0017"},{"key":"e_1_3_7_13_2","doi-asserted-by":"publisher","DOI":"10.1017\/jfm.2013.464"},{"key":"e_1_3_7_14_2","doi-asserted-by":"publisher","DOI":"10.5772\/1820"},{"key":"e_1_3_7_15_2","doi-asserted-by":"publisher","DOI":"10.1017\/jfm.2011.138"},{"key":"e_1_3_7_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9290(00)00218-9"},{"key":"e_1_3_7_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-6105(01)00158-1"},{"key":"e_1_3_7_18_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022112010005306"},{"key":"e_1_3_7_19_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-28968-2_18"},{"key":"e_1_3_7_20_2","doi-asserted-by":"publisher","DOI":"10.1112\/S0025579309000473"},{"key":"e_1_3_7_21_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspa.2010.0303"},{"key":"e_1_3_7_22_2","doi-asserted-by":"publisher","DOI":"10.1098\/rsta.2011.0092"},{"key":"e_1_3_7_23_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspa.2016.0164"},{"key":"e_1_3_7_24_2","doi-asserted-by":"publisher","DOI":"10.1017\/jfm.2016.706"},{"key":"e_1_3_7_25_2","unstructured":"Balta S. 2017 On fluid-body and fluid-network interactions.
