An image analysis technique was used to evaluate mixture homogeneity at four target areas. Numerical simulations were found to be a useful support for the design phase, since a general idea of mixing of fluids can be inferred from the segregation or the distribution of path lines. Comparison with a well-known mixer, the Tear-drop one, was also performed. Over the examined range of Reynolds numbers 1  \u2264 Re \u2264 100, the Y-Y and H-C mixers showed at their exit an almost flat mixing index characteristic, with a mixing efficiency higher than 90%; conversely the Tear-drop mixer showed a relevant decrease of efficiency at mid-range. Furthermore, the Y-Y and the H-C showed significantly less pressure drop than the Tear-drop mixer.<\/jats:p>","DOI":"10.3390\/mi6081166","type":"journal-article","created":{"date-parts":[[2015,8,18]],"date-time":"2015-08-18T10:31:11Z","timestamp":1439893871000},"page":"1166-1179","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Comparative Analysis of Passive Micromixers at a Wide Range of Reynolds Numbers"],"prefix":"10.3390","volume":"6","author":[{"given":"Vladimir","family":"Viktorov","sequence":"first","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering (DIMEAS), Politecnico di Torino, Corso Duca degli Abruzzi 24, 10129 Turin, Italy"}]},{"given":"Md","family":"Mahmud","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering (DIMEAS), Politecnico di Torino, Corso Duca degli Abruzzi 24, 10129 Turin, Italy"}]},{"given":"Carmen","family":"Visconte","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering (DIMEAS), Politecnico di Torino, Corso Duca degli Abruzzi 24, 10129 Turin, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2015,8,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1016\/j.compfluid.2014.03.003","article-title":"Numerical investigation of mixing performance in microchannel T-junction with wavy structure","volume":"96","author":"Solehati","year":"2014","journal-title":"Comput.
