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", "download_preview_message": "", "file_order": 0, "filename": "Min Han Htet (JIME).pdf", "filesize": [{"value": "989 KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 989000.0, "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"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000007092", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-12-29"}, "publish_date": "2020-12-29", "publish_status": "0", "recid": "7092", "relation": {}, "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_shared_id": -1}
