The other pipe is filled with PCM and the system is heated from the inner sinusoidal pipe at different temperatures. The main aim of the study is to control the melting time. The finite volume method (FVM) is used to solve time-dependent governing equations. Four different cases are chosen for the sinusoidal wall to see the effects of geometry on melting. After the analysis, it is observed that melting time can be controlled via an adjustment of the geometrical parameter, namely a passive technique, without spending extra energy.<\/jats:p>","DOI":"10.3390\/sym15010129","type":"journal-article","created":{"date-parts":[[2023,1,2]],"date-time":"2023-01-02T04:17:38Z","timestamp":1672633058000},"page":"129","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Analysis of the Melting Time of Phase Change Material in a Heat Exchanger with Sinusoidal Inner Duct"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2161-0639","authenticated-orcid":false,"given":"Hakan F.","family":"\u00d6ztop","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Technology Faculty, F\u0131rat University, Elazig 23119, Turkey"},{"name":"Department of Mechanical Engineering, Faculty of Engineering, King Abdulaziz University, Jeddah 21589, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00d6mer","family":"Akbal","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Technology Faculty, F\u0131rat University, Elazig 23119, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatih","family":"Selimefendigil","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Engineering Faculty, Manisa Celal Bayar University, Manisa 45040, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4852-2217","authenticated-orcid":false,"given":"Nidal H.","family":"Abu-Hamdeh","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, King Abdulaziz University, Jeddah 21589, Saudi Arabia"},{"name":"K.
