The experiment was carried out at a pressure range of 0.6 and 1.2MPa with mass velocities of 90 and 180kg/m^2 s, in which the vapor quality varied from 0 to 1. The void fraction was measured by means of simultaneously closing valves of both sides of the test tube at adiabatic condition. Experimental results for the micro-fin tube were compared with previous correlations for smooth tube. It was found that experimental data of the micro-fin tube were lower than predicted results using correlations for smooth tube. As a trial, an empirical correlation was proposed, based on the present experimental results. The observation of the flow pattern through a sight glass was also carried out with a camera. The observation results were compared with modified Baker's map.","PeriodicalId":22886,"journal":{"name":"The reports of Institute of Advanced Material Study Kyushu University","volume":"31 1","pages":"79-85"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82867350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The higher temperature of spinning enhanced the refonnation through the lower viscosity. The thinner lobe emphasized the die-swelling through the larger shear rate, which reduces the viscosity, although the nozzles of the present study had the same cross-sectional area. Shape factors of the nozzle and fiber rescribe the extents of cause and results of die-swelling, respectively. Die-swelling is found to change the radial type alignment of the constituent domains to random order. The degrees of preferred orientation along the fiber axis were slightly influenced by die-swelling. The pressure in spinning and the nozzle shape were correlated to the reformation extent of the resultant fiber.","PeriodicalId":22886,"journal":{"name":"The reports of Institute of Advanced Material Study Kyushu University","volume":"60 1","pages":"7-11"},"PeriodicalIF":0.0,"publicationDate":"1999-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86595802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
