A theoretical and experimental study is conducted to discuss the wringing mechanism. The liquid film may be separated into a large number of small puddles when two surfaces are rubbed together. One can expect a large adhesive force due to the resultant of surface tension acting on the circumference of each puddle. Numerical results for oil distribution between two surfaces show that the total perimeter length of liquid film reaches 10500 m on the surface of 3cm, which leads to 1.0×10 (N/m) for the adhesive force. The adhesive forces measured experimentally roughly agree with the theoretical value. A simple model is proposed to explain the adhesive force dependence on the velocity of pulling apart two surfaces.","PeriodicalId":282024,"journal":{"name":"Journal of the Japanese Society for Experimental Mechanics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130651443","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}

This means that the burner pitch of 2.5 mm is close enough to cause flame-flame interaction to get over the limit of burner diameter and establish clustered microflames. It is found that the NOx emission from clustered microflames is quite low, as low as 6 to 10 ppm at 0% O2, while the CO emission is high level. The NOx and CO emissions from the clustered microflames show different correlation line from other types of burner flames including diffusion microflame.","PeriodicalId":282024,"journal":{"name":"Journal of the Japanese Society for Experimental Mechanics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114733515","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}

In this work, we focus on the reductive removal by using immiscibility of iron and calcium. The oxygen partial pressure is expected to be kept under 10 -20 atm by the introduction of calcium alloy phase, which can enhance the reductive removal of impurities in molten iron. In this work, we examine the possibility of the reductive removal of impurities by the use of the calcium alloy phase.","PeriodicalId":282024,"journal":{"name":"Journal of the Japanese Society for Experimental Mechanics","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115846201","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}
