 note = {In processing synthetic fiber yarn, a lot of rollers are rotated at high-speed. Power loss for rotating such rollers has become larger and larger according to increasing yarn processing speed. Former studies proposed that power consumption for rotating yarn package might be reduced by 30% by locating the cover around it in order to limit the air flow. It is important to limit the air flow for saving power consumption. Now it becomes possible to calculate much more complex flow because of development of both the hard-ware of the personal computer and the software for computational fluid dynamics (CFD) analysis. The present study focused on air flows around a single drawing roller as the first step of a series of studies in which we are going to numerically analyze air flows around drawing rollers to clarify the effect of structures of their covers on the reduction of power consumption to rotate them. The comparison of experimentally measured power consumption with corresponding computational results has identified the validity of the present CFD analysis. The CFD analysis also confirmed that the energy-saving effect of the cover exists even if there is a slit on the cover in order to thread air stream caused by high-speed yarn running., 出版者照会後に全文公開, 金沢大学理工研究域機械工学系},
