\nBased on a review of the literature and patent solutions in the field of static mixers, as well as on CFD calculations,
\nthree variants of inserts were developed: a twisted lattice baffle, a twisted solid baffle, and a composite insert
\ncombining both concepts.
\nIn the experimental part, a prototype test installation was built and the pressure drop in the mixer was measured for
\nvarious insert configurations, as well as for a Kenics-type insert and for an empty pipe. On this basis, the friction factor
\nf and the pressure drop coefficient Z were determined as functions of the Reynolds number. The results indicate that the
\ncomposite insert with counter-rotating solid and lattice sections provides pressure drops comparable to a classical
\nKenics insert, while ensuring favourable velocity and pressure fields in the near-wall region. The potential applications
\nof the new insert in central heating installations, domestic hot water systems, refrigeration installations and renewable
\nenergy systems are discussed.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[995,4949,4951,4952,4322,4950],"tematyka":[1143],"class_list":["post-24168","artykul","type-artykul","status-publish","hentry","tag-cfd","tag-mixing","tag-mixing-insert","tag-pressure-drop","tag-reynolds-number","tag-static-mixer","tematyka-cold-and-hot-water-and-heating-systems","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["MARIAN KORDAS","KONRAD WITKIEWICZ","ANNA KIE\u0141BUS-R\u0104PA\u0141A","WOJCIECH IGNACZAK","MAGDALENA CZAJKOWSKA","RAFA\u0141 RAKOCZY","PIOTR JAWORSKI"],"ptb_artykul_text_2":"10.36119\/15.2025.12.5","ptb_artykul_numer_miesi_cznika":"12\/2025 Instal pp.33-37","ptb_artykul_info_autor":"dr hab. in\u017c.
