- die wall friction 模壁摩擦
- The effect of curvature, torsion and Dean number on secondary flow, the isoline of stream function, the distribution of axial speed and wall friction is discussed in detail. 详细讨论了曲率、挠率、Dean数对二次流动、流函数等值线和轴向速度的分布以及壁面摩擦力的影晌。
- The influences on mechanical property of die wall lubrication procedure were compared to admixed powder lubrication method. 对比了模壁润滑与粉末润滑对模压制品的力学性能影响。
- In the impingement experiments, the spray were impinged on the wall using a single hole, spray kept on moving alone the wall, and vortex was observed as a result of gas resistance and wall friction. 油束撞击到平板受到平板的限制,形成壁面喷射,油束沿壁面运动,由于受到壁面上方空气的阻力而部分油束脱离平板形成“卷毡”现象,油束卷起的高度即壁面高度远小于壁面贯穿距离。
- The sticking point about the problems is the no-slip adhesive shearing extrusion mechanism adopted in normal extrusion and big resistance appears at the interface of die wall and polymer melt. 产生以上问题的根源在于传统挤出技术采用非滑移粘着剪切口模挤出方式,使得口模壁面对挤出熔体的阻力大。
