- 論文の詳細を見る
This paper is a report on experimental results concerning the relationship between the fiber concentration of pulp suspension flow and the flow velocity for different shapes of turbulence generating means (orifice plate). The instantaneous concentration variation as spatially averaged in the duct width direction was measured by an optical method. The results show : (1) the upstream condition affects the fiber concentration unevenness cY^^' on the downstream side over a long distance ; and (2) the increment of cY^^' from its limit value cE^^', or " cY^^' - cE^^'', is well-correlated with a simply defined non-Newtonian Reynolds number, which can be easily determined.
