For this purpose, a new concept of cargo ship which is called Ultra\nLarge Block coefficient Ship (ULBS) Cb≥0.95 is used as the basic ship and\nits bow is modified by adding a bulbous bow. Since ULBS is a very blunt\nship and is designed to sail at low-speed, it will have large wave-breaking\nin front of the bow. As it is stated that the protruded bows are effective in\nreducing steepness of bow waves and also contribute to the reduction of\nwave breaking resistance, in the present study, a bulbous bow is\nconsidered as an example of flow control devices and is attached to ULBS\nmodels in order to reduce the wave-breaking at the bow of ULBS. Then,\nthe wave making resistance coefficient, integration of the square of free\nsurface elevations, and the square of free surface disturbance function\nD(x,y)-values which are related to the wave-breaking phenomena are\ncalculated using Rankine source method and Baba’s low speed theory\nrespectively for ULBS models with protruded bows in full load and ballast\nconditions. The calculated results are compared with those of non-bulbous\nbow ULBS models. The wave making resistance coefficient results of\nULBS models with bulb appear to reduce in the case of full load condition\nbut increase in the case of ballast condition. The integration of square of\nfree surface disturbance function and wave elevation values of ULBS\nmodels with bulb, increase for both full load and ballast conditions\ncompared to those without bulb."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"Bulbous Bow, Free Surface Disturbance Function, Ultra Large Block coefficient Ship (ULBS), Wave-making, Wave-breaking"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2021-01-04"}],"displaytype":"preview","filename":"International Conference paper ICSE 2019 (Study on Wave-Breaking Phenomena of Full hull forms with and without Protruded Bows) .pdf","filesize":[{"value":"654 KB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/7173/files/International Conference paper ICSE 2019 (Study on Wave-Breaking Phenomena of Full hull forms with and without Protruded Bows) .pdf"},"version_id":"4041211b-dcae-43fc-9989-d77f87a6e138"}]},"item_1583103147082":{"attribute_name":"Conference papers","attribute_value_mlt":[{"subitem_acronym":"ICSE 2019","subitem_c_date":"December 7-8, 2019","subitem_conference_title":"The Tenth International Conference on Science and Engineering, 2019 ( 10 th ICSE 2019)","subitem_part":"I","subitem_place":"Yangon Technological University, Yangon, Myanmar","subitem_session":"Manufacturing and Automation","subitem_website":"http://www.ytu.edu.mm/icse"}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{"subitem_book_title":"Proceedings of Conference on the 10 th International Science and Engineering 2019","subitem_isbn":"978-99971-0-790-9","subitem_pages":"366-370","subitem_place":"Yangon Technological University","subitem_publisher":"Yangon Technological University, JICA"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Aye Aye Mon"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Conference paper"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2019-12-07"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"https://www.researchgate.net/profile/Aye_Mon10"},"item_title":"Study on Wave Breaking Phenomena of Full Hull Forms with and without Protruded Bows","item_type_id":"21","owner":"155","path":["1608151108672","1608152048756"],"publish_date":"2021-01-04","publish_status":"0","recid":"7173","relation_version_is_last":true,"title":["Study on Wave Breaking Phenomena of Full Hull Forms with and without Protruded Bows"],"weko_creator_id":"155","weko_shared_id":-1},"updated":"2021-12-13T02:44:20.009448+00:00"}
