The typical nonlinear pool boiling CHF data based on hydrodynamic instability (HI) mechanism for a horizontal cylinder with a 1.2 mm diameter due to exponential heat inputs,  with the period of 20 s (namely, quasi steady heat inputs) in a pool of water at pressures with measured CHFs data described that there was newly CHF mechanism, namely, heterogeneous spontaneous nucleation (HSN) firstly suggested by Sakurai and Fukuda et al. The general trend of CHF is such that: the CHF for subcoolings at a pressure first increased up to the maximum CHF, secondly decreased down to minimum CHF, and finally again increased monotonously with an increase in subcooling at low, middle (transition) and high subcoolings respectively. The photographic studies between low and high subcooling as well as middle subcooling at different pressures respectively have been carried out recently. However, the CHFs for middle subcoolings for wide ranges of pressures became insignificant because they were influenced by different degrees of subcooling for low, middle and high pressures. Moreover, the transition from high CHF to low CHF were observed independence of pressure for a steady heat inputs and pre-pressurization before each experimental run. In this study, the photographic study for pressures at 199, 1082 and 2063 kPa for a subcooling of 80 K were carried out to observe the vapor behavior of each CHF. It was confirmed that the vapor behavior of 199 kPa for subcooling of 80 K were extremely different from other higher pressures due to occurrence of a very small bubble emission explosively from a single bubble. The rate of bubble growth and detachment for both higher pressures were also different each other. It was generally assumed that the vapour behaviour were dependent on pressure although there was no significant difference between heat inputs and pre-pressurization."}]}, "item_1583103147082": {"attribute_name": "Conference papers", "attribute_value_mlt": [{"subitem_acronym": "ISTP-24", "subitem_c_date": "1-5 November 2013", "subitem_conference_title": "The 24th International Symposium on Transport Phenomena", "subitem_place": "Yamaguchi, Japan"}]}, "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": "Conference paper"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2013-11-01"}, "item_title": "PHOTOGRAPHIC STUDY OF SUBCOOLED POOL BOILING CHF FOR PRE-PRESSURIZATION BEFORE EACH EXPERIMENTAL RUN", "item_type_id": "21", "owner": "155", "path": ["1608152094107"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000007680", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2021-01-21"}, "publish_date": "2021-01-21", "publish_status": "0", "recid": "7680", "relation": {}, "relation_version_is_last": true, "title": ["PHOTOGRAPHIC STUDY OF SUBCOOLED POOL BOILING CHF FOR PRE-PRESSURIZATION BEFORE EACH EXPERIMENTAL RUN"], "weko_shared_id": -1}
