An analytical solution was obtained for the average gas-phase Sherwood number ShG as a function of the gas-phase Graetz number GzG and the dimensionless inter facial gas velocity U. This analysis, however, is not applicable to the case of U>2 where circulation exists in the gas phase. The purpose of this short paper is to present an approximate analytical solution for the present case and to confirm this approximate solution experimentally.","PeriodicalId":9388,"journal":{"name":"Bulletin of the University of Osaka Prefecture, Series A Engineering and Natural Sciences","volume":"54 2","pages":"79-89"},"PeriodicalIF":0.0,"publicationDate":"1978-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91424013","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 observations of etchpits are made on the surfaces parallel to the (111) plane or the surfaces cut out parallel to the (111) and (111) planes of each specimen where the (111) plane is the primary slip plane. As the Al concentration increases the multiplied dislocations tend to arrange along the traces of the intersections between the observed surface and the slip planes. The distribution of the primary dislocation of the primary disloccrimary disloccations observed on the {111} plane other than the (111) plane changes from the Cu type to the Liider's band propagation type as the Al concentration is increased. On the (111) plane the dislocations lying on the (111) plane are observed early in stage L but the dislocations lying on the (111) and (111) planes are multiplied inhomogeneously in the transition region from stage I to stage II. These results may suggest the formation of the Lomer-Cottrell dislocations at this strain. The density of the dislocations observed on the (111) plane is higher than that on the (111) plane, but the difference is lessened with increasing strain. If the Cu-2.5 at % Al composition, the density of dislocations b erved on these two planes 19 of the same order at the beginning of stage II, while in the Cu-15 at % Al composition there is a larger difference between th em even at the largest stress applied. In stage I the dislocation density is proportional to the shear stress. In stage II the square root of the dislocation density is proportional to the shear stress.
