This research was undertaken as a basic test of a screen-type model, in which a circular cylinder has been inserted in a channel. The test was performed using a pulp liquid with a fiber concentration ranging from 0.3 to 1.0 wt% under flow velocity conditions of Ua = 0.016 0.74 m/s. The distributions of the fiber concentration were measured by transmitted light attenuation method. The obtained results are illustrated, and the influence of the flow velocity on the characteristics of the wake behind the cylinder are argued with reference to findings previously reported (Sumida and Fujimoto, 2010). The fiber-concentration distribution changes in the flow direction were large in the section from the cylinder to four times its diameter. The findings provide useful information for the development of hydraulic headboxes., Ⅲ.論文集, application/pdf}, pages = {71--75}, title = {〈原著論文〉パルプ繊維分散促進プロモータ後流領域における繊維濃度分布}, volume = {9}, year = {2018}, yomi = {スミダ, マサル and フジモト, タロウ} }
