The exponential period,τ , was\nvaried from 5 ms to 20 s. The platinum ribbons having different surface conditions, namely, commercial\nsurface (CS), treated surface-I (TS-I) and treated surface-II (TS-II) were utilized as test heaters. For\nsurface conditions, the values of contact angle and surface roughness were measured prior to pool boiling\nexperiments. The TS-II was subjected to conditions without pre-pressurization and with\npre-pressurization up to 4.4 MPa before each experimental run was carried out. It is assumed that the\ncontact angle is a major contributor to increasing CHF at quasi-steadily heat input. The TS-II enhanced\nthe heat transfer performance ~ 290 % and ~ 430 %, and CHF of 1.2 times and 1.5 times relative to CS\nand TS-I, respectively. It was shown that transition of heat transfer processes and transient CHF depend\non surface conditions, heat generation period and pre-pressurization. The transient CHF due to surface\nconditions was compared with corresponding values."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"critical heat flux"},{"interim":"transient pool boiling heat transfer"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-12-29"}],"displaytype":"preview","filename":"Min Han Htet (JIME).pdf","filesize":[{"value":"989 KB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/7092/files/Min Han Htet (JIME).pdf"},"version_id":"a379a845-a6f7-40f0-a80d-d65936578d2e"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"Japan Institute of Marine Engineering","subitem_journal_title":"Journal of JIME","subitem_pages":"77-88","subitem_volume":"Vol.50, No.6 (2015)"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Min Han Htet"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2015-05-09"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"https://doi.org/10.5988/jime.50.782"},"item_title":"Experimental Study on Transient Boiling Heat Transfer and Critical Heat Flux on Horizontal Vertically-Oriented Ribbon with Different Surfaces under Atmospheric Conditions","item_type_id":"21","owner":"155","path":["1608152094107"],"publish_date":"2020-12-29","publish_status":"0","recid":"7092","relation_version_is_last":true,"title":["Experimental Study on Transient Boiling Heat Transfer and Critical Heat Flux on Horizontal Vertically-Oriented Ribbon with Different Surfaces under Atmospheric Conditions"],"weko_creator_id":"155","weko_shared_id":-1},"updated":"2021-12-13T02:28:09.246102+00:00"}
