The dynamic chaotic flow is obtained from two\u2010dimensional (2D) computational fluid dynamics simulations, for different Reynolds numbers, of a confined impinging jets mixer. POD enables reconstruction of the dynamic flow from a few modes that are related to coherent flow structures. The POD flow reconstruction enables a large compression of the flow data set. The decomposition of the flow field into orthogonal modes related to coherent structures provides direct insight into the mixing dynamics and scales which are not accessible from flow dynamics statistic quantities, which were introduced in the context of turbulence and are here applied to chaotic flow.<\/jats:p>","DOI":"10.1002\/ceat.201900050","type":"journal-article","created":{"date-parts":[[2019,5,7]],"date-time":"2019-05-07T10:54:33Z","timestamp":1557226473000},"page":"1709-1716","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Proper Orthogonal Decomposition and Statistical Analysis of 2D Confined Impinging Jets Chaotic Flow"],"prefix":"10.1002","volume":"42","author":[{"given":"Pedro","family":"Torres","sequence":"first","affiliation":[{"name":"Universidade do Porto Faculdade de Engenharia, Department of Chemical Engineering, Laboratory of Separation and Reaction Engineering, Associate Laboratory LSRE-LCM  Rua Dr. Roberto Frias 4200-465 Porto Portugal"},{"name":"The University of Manchester School of Chemical Engineering &amp; Analytical Science  Oxford Road M13\u20099PL Manchester UK"}]},{"given":"Nelson D.","family":"Goncalves","sequence":"additional","affiliation":[{"name":"Universidade do Porto Faculdade de Engenharia, Department of Chemical Engineering, Laboratory of Separation and Reaction Engineering, Associate Laboratory LSRE-LCM  Rua Dr. Roberto Frias 4200-465 Porto Portugal"}]},{"given":"Claudio P.","family":"Fonte","sequence":"additional","affiliation":[{"name":"The University of Manchester School of Chemical Engineering &amp; Analytical Science  Oxford Road M13\u20099PL Manchester UK"}]},{"given":"Madalena M.","family":"Dias","sequence":"additional","affiliation":[{"name":"Universidade do Porto Faculdade de Engenharia, Department of Chemical Engineering, Laboratory of Separation and Reaction Engineering, Associate Laboratory LSRE-LCM  Rua Dr. Roberto Frias 4200-465 Porto Portugal"}]},{"given":"Jos\u00e9 Carlos B.","family":"Lopes","sequence":"additional","affiliation":[{"name":"Universidade do Porto Faculdade de Engenharia, Department of Chemical Engineering, Laboratory of Separation and Reaction Engineering, Associate Laboratory LSRE-LCM  Rua Dr. Roberto Frias 4200-465 Porto Portugal"}]},{"given":"Alain","family":"Lin\u00e9","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Toulouse LISBP, INSA, INRA, CNRS  Toulouse France"}]},{"given":"Ricardo J.","family":"Santos","sequence":"additional","affiliation":[{"name":"Universidade do Porto Faculdade de Engenharia, Department of Chemical Engineering, Laboratory of Separation and Reaction Engineering, Associate Laboratory LSRE-LCM  Rua Dr. Roberto Frias 4200-465 Porto Portugal"}]}],"member":"311","published-online":{"date-parts":[[2019,6,12]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1006\/jsvi.2001.4041"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511622700.004"},{"key":"e_1_2_7_4_1","first-page":"76","volume":"7","author":"Kosambi D.
