	1	Study on Local Resistance of non-Newtonian Power Law Fluid in Elbow Pipes显示文摘This paper focuses on the flow characteristic and local resistance of non-Newtonian power law fluid in a curved90° bend pipe with circular cross-sections,which are widely used in industrial applications.By employing numerical simulation and theoretical analysis the properties of the flow and local resistance of power law fluid under different working conditions are obtained.To explore the change rule the experiment is carried out by changing the Reynolds number,the wall roughness and different diameter ratio of elbow pipe.The variation of the local resistance coefficient with the Reynolds number,the diameter ratio and the wall roughness is presented comprehensively in the paper.The results show that the local resistance force coefficient hardly changes with Reynolds number of the power law fluid;the wall roughness has a significant impact on the local resistance coefficient.As the pipe wall roughness increasing,the coefficient of local resistance force will increase.The main reason of the influence of the roughness on the local resistance coefficient is the increase of the eddy current region in the power law fluid flow,which increases the kinetic energy dissipation of the main flow.This paper provides theoretical and numerical methods to understand the local resistance property of non-Newtonian power law fluid in elbow pipes.

	2	基于ANSYS的90°管道弯头有限元分析显示文摘利用有限元软件ANSYS建立了90°XGQT01-76.1弯头三维实体参数化有限元模型。通过对弯头实体模型的强度分析得出了弯头在受载时的应力分布情况,根据应力分布状况得出弯头易发生破坏的位置及破坏形式,在这些位置应进行局部加固或避免生产过程中的局部减薄现象。由弯头强度分析得出其最大等效应力远小于材料屈服值,利用参数化模型减小弯头壁厚并对其进行应力分析得出了弯头壁厚的最优值所在区间。	王金龙陈俊龙	2016	潍坊学院学报2016，16，2：	3
