In the experiments, we investigate the flow characteristics in three sudden-expansion ducts and examine the influences of the expansion ratio and the flow rate on the behavior of the pulp fibers. The changes in the distributions of time-averaged concentration and the fluctuations of the concentration along the duct axis are illustrated for the pulp suspensions with various concentrations. Moreover, we discuss the degree of nonuniformity of the fiber concentration. The results obtained from this study are useful basic data and are expected to contribute to improving and optimizing headbox of the papermaking machines., 研究種目：基盤研究(C);  研究期間：2011～2013;   課題番号：23560212;   研究分野：工学;   科研費の分科・細目：機械工学・流体工学, application/pdf},
