By injecting the dispersed phases containing the reactants, the mixing can be tuned separately, thus a higher control over reactions inside the droplets is achievable. The numerical investigation of such multi-phase and multi-component systems proposes various challenges, since the concentrations of species also depend on the distribution of phases. In this article, we investigate the concentration distribution of the species in microfluidic droplet generators both experimentally and theoretically. Besides the characterization of the distribution of the dispersed and continuous phases, we have also studied the effect of injection rates on mixing inside the droplets. The size of the droplets decreases on increasing the flow rate of the oil phase and increases on increasing the flow rate of water phase compared to the oil phase. The numerical analysis based on solving the Navier–Stokes equation with volume-of-fluid method including a diffusive component in the aqueous phase corroborated the experimental findings. Furthermore, by determining the contribution of various transport processes to mixing of reactants inside the dispersed phases, we have shown that convection is dominant inside the droplets for all parameters used. © 2025 The Authors true 2025 true true true false true false GOLD 2026-05-24 true https://doi.org/10.1016/j.ijmultiphaseflow.2025.105277 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Q1 false false false false 2025-06-10T07:04:15.471+0000 Alkalmazott és Környezeti Kémiai Tanszék (SZTE / TTIK / KI); Fizikai Kémiai és Anyagtudományi Tanszék (SZTE / TTIK / KI) 5 12 2 6 0 true Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 126865487 /api/authorship/126865487 1 0.167 true false false Author 10074723 /api/author/10074723 Papp Paszkál true true Papp P. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 126865488 /api/authorship/126865488 2 0.16666667 false false false Pecze L. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 126865489 /api/authorship/126865489 3 0.167 false false false Author 10069335 /api/author/10069335 Lantos Emese true true Lantos E. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 126865490 /api/authorship/126865490 4 0.167 false false false Author 10096681 /api/author/10096681 Tóth Petra true true Tóth P. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 126865491 /api/authorship/126865491 5 0.167 false false false Author 10001652 /api/author/10001652 Tóth Ágota true 10001652 true Tóth Á. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 126865492 /api/authorship/126865492 6 0.167 false true true Author 10001668 /api/author/10001668 Horváth Dezső true 10001668 true Horváth D. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 29471391 /api/publicationidentifier/29471391 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.1016/j.ijmultiphaseflow.2025.105277 https://doi.org/10.1016/j.ijmultiphaseflow.2025.105277 false true PublicationIdentifier 29489644 /api/publicationidentifier/29489644 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001502374900001 https://www.webofscience.com/wos/woscc/full-record/001502374900001 true true PublicationIdentifier 29471390 /api/publicationidentifier/29471390 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 105005867300 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105005867300 false true PublicationIdentifier 30019025 /api/publicationidentifier/30019025 SwordSource 90 /api/publicationsource/90 PublicationSourceType 10007 /api/publicationsourcetype/10007 true true true SZTE Publicatio SZTE Publicatio http://publicatio.bibl.u-szeged.hu/@@@ true true 90 true GREEN true IDENTICAL 38115 http://publicatio.bibl.u-szeged.hu/38115 false true Keyword 5703 /api/keyword/5703 true 5703 true Keyword 1013389 /api/keyword/1013389 true 1013389 true Keyword 1013389 /api/keyword/1013389 true 1013389 true Keyword 1013534 /api/keyword/1013534 true 1013534 true Keyword 1033366 /api/keyword/1033366 true 1033366 true Keyword 1066900 /api/keyword/1066900 true 1066900 true Keyword 1302505 /api/keyword/1302505 true 1302505 true Keyword 1315482 /api/keyword/1315482 true 1315482 true Keyword 1711703 /api/keyword/1711703 true true Keyword 1737046 /api/keyword/1737046 true true Keyword 1956355 /api/keyword/1956355 true true Keyword 1956495 /api/keyword/1956495 true true Keyword 2316772 /api/keyword/2316772 true true Keyword 2636497 /api/keyword/2636497 true true Keyword 2999223 /api/keyword/2999223 true true Keyword 3612267 /api/keyword/3612267 true true Keyword 3876537 /api/keyword/3876537 true true SjrRating 11582986 /api/sjrrating/11582986 17 0.24 journal RatingType 10002 /api/ratingtype/10002 sjr true true ClassificationExternal 1507 /api/classificationexternal/1507 true 1507 true Q1 DIRECT true true /api/publication/36185718 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Forrásközlemény" style="float: left" src="/frontend/resources/grid/publication-core-icon.png"> <div class="autype autype0"> <span class="author-name" mtid="10074723"><a href="/gui2/?type=authors&mode=browse&sel=10074723" target="_blank">Papp P.
