1PIV measurements of turbulent jets issuing from triangular and circular orifice plates显示文摘The present study experimentally investigated the near-field flow mixing characteristics of two turbulent jets issuing from equilateral triangular and circular orifice plates into effectively unbounded surroundings,respectively.Planar particle image velocimetry(PIV) was applied to measure the velocity field at the same Reynolds number of Re=50,000,where Re = UeDe /with Ue being the exit bulk velocity and the kinematic viscosity of fluid,D e the equivalent diameters.The instantaneous velocity,mean velocity,Reynolds stresses were obtained.From the mean velocity field,the centreline velocity decay rate and half-velocity width were derived.Comparing the mixing characteristics of the two jets,it is found that the triangular jet has a faster mixing rate than the circular counterpart.The triangular jet entrainments with the ambient fluid at a higher rate in the near field.This is evidenced by a shorter unmixed core,faster Reynolds stress and centreline turbulence intensity growth.The primary coherent structures in the near field are found to break down more rapidly in the triangular jet as compared to the circular jet.Over the entire measurement region,the triangular jet maintained a higher rate of decay and spread.Moreover,all components of Reynolds stress of the triangular jet appear to reach their peaks earlier,and then decay more rapidly than those of the circular jet.In addition,the axis-switching phenomenon is observed in the triangular jet.XU MinYi ZHANG JianPeng MI JianChun NATHAN G J KALT P A M 2013Science China(Physics,Mechanics & Astronomy)2013,56,6:7
2定期运动有助于改善高血压患者蛋白质稳态、炎症和血管活性显示文摘体育锻炼是一种公认的非药物控制血压的策略,除了降低血压外,运动还能对高血压患者的炎症特征、自主功能、内皮功能和抗氧化状态产生积极的影响。但其对高血压患者的蛋白质稳态的影响尚不清楚。已有动物研究表明,运动训练干预可以改善蛋白质质量控制机制,但在动物模型中报告的积极作用仍有待于在人类身上得到证实。本研究旨在根据报告的运动习惯,评估患高血压成年人的蛋白质稳态,生活质量以及炎症、氧化应激和血管活性生物标记物状态。Teixeira M Gouveia M Duarte A Ferreira M Simões MI Conceição M Silva G Magalhães S Ferreira R Nunes A Vieira SI Ribeiro F 周卫(译) 叶鹏(审校) 2020中华高血压杂志2020,28,12:2
