As the model PCB, o-dichlorobenzene was used. The solvent was hexane or dodecane. Wood chips impregnated with o-dichlorobenzene were used as the sample. The ultrasonic and solvent conditions were changed, and the removal ratio of o-dichlorobenzene from sample was measured. In order to examine the removal behavior of chlorinated organic compound from pore, the Stefan tube injected with o-dichlorobenzene was used as the sample. The pore and solvent conditions were changed, the interface position between o-dichlorobenzene and solvent in Stefan tube was measured and the penetration depth of solvent in Stefan tube was determined.By the ultrasonic irradiation, the removal ratio rapidly increased and became almost unity after 120 minutes for the sample with 10 mm in length. The removal rate for the ultrasonic irradiation was much higher than that for the shaking. The difference in removal ratio between the ultrasonic irradiation and the shaking became larger as the sample was bigger. The removal ratio increased with increasing sound pressure amplitude and became constant beyond a certain sound pressure amplitude. At the fixed sound pressure amplitude, the removal ratio at 28 kHz was nearly equal to that at 45 kHz. The removal ratio hardly depended on the solvent temperature. The removal ratio for degassed solvent was larger than that for non-degassed solvent.The penetration depth in Stefan tube had a maximum value against location of Stefan tube in solvent, but had no significant influence on size and depth of pore in Stefan tube. When the saturation degree of dissolved oxygen in solvent was 0.65, the penetration depth in Stefan tube was largest.","PeriodicalId":381569,"journal":{"name":"Progress in Multiphase Flow Research","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128549582","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 the technique, viscosity of levitated sample has been estimated from the damping constant time with an oscillating drop method based on linear approximations. However, this method is limited to low-viscosity fluids because the oscillation could not be excited to a highly viscous liquid drop. The measurement method which can be applied to viscosity over the entire range possible has not been established yet. The main purpose of the present study is to investigate the possibility to measure viscosity of entire range with a levitating liquid drop. In the present study, viscous drops were levitated by the electrostatic force. The effect of viscosity on the deformation of a rotating liquid drop was experimentally investigated. As a result, the rotational deformation of a low-viscosity drop is found to be qualitatively similar to the numerical result. On the other hand, large differences from the numerical result are observed in the case of high-viscosity drops. It is confirmed especially that viscosity is closely related to the evolution of drop shape during the drop breakup process. From the experimental results, it is clarified that the viscosity of a levitating liquid drop can be estimated from the breakup behavior of the drop.","PeriodicalId":381569,"journal":{"name":"Progress in Multiphase Flow Research","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123830124","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}

Ltd. located in the east of Kochi Prefecture produces salt and mineral liquid by the solar evaporation process with Muroto Deep Sea Water. This method has an advantage of making high quality salt and mineral to meet the demand of customers. But on the other hand, this has some problem for intentional production and mass production under the influence of the weather. Therefore, this study are aimed to develop a significant industrial production process of salt and mineral to get a equal quality of existing ones produced by the solar evaporation process with Deep Sea Water, which shall be realized to be able to make a intentional and mass production with more low cost. Particularly, this paper presents the multiple-effective Vacuum-evaporator which is one of the concentrators. We define this multiple-effective Vacuum-evaporator as a process device to extract gypsum from concentrated deep sea water, and make decision for density of concentrated water. And also, we have practical inspection for automatic concentration operation. The results are summarized as follows: (1) Acceptable production tolerance was controlled by less than 10% as a result of practical inspection for concentrated Deep Seawater waste at the boiling point of multiple-effective Vacuum-evaporator based on the target of Baume's value 10. (2) When we studied about concentrated control using by the conductivity meter, we got the result in error value by less than ±0.2 and in tolerance ratio by less than 2% against target of Baume's value 10. It means to be possible to produce salt and mineral using by Deep Seawater Waste to meet precisely with target concentration density.","PeriodicalId":381569,"journal":{"name":"Progress in Multiphase Flow Research","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127386983","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}
