1边界层吸气对压气机叶栅角区分离损失的控制显示文摘压气机角区的大范围回流通常会引起叶片通道中的三维阻塞现象,并伴随有强烈的掺混流动损失。采用德国航空航天中心(DLR)开发的TRACE程序,在其推进技术研究所的高速压气机叶栅试验台(包含5个NACA65K48直叶片)上,研究了位于端壁上的边界层吸气措施——叶片弦中近尾缘吸气槽(MTE)对该直压气机叶栅通道的角区分离进行控制,减小二次流动损失,进而削弱其对总损失的影响。通过基于定常雷诺平均Navier-Stokes(RANS)方法的数值模拟研究与相应的试验研究对比,端壁边界层吸气能够较好地重新组织角区气流流动,减弱附着于叶片吸力面尾缘的集中脱落涡,使得角区分离涡强度显著降低,由此引起的二次流损失也明显降低,与无吸气状态相比最大降幅可达81.2%;在设计状态下采用吸气流量率为1%的MTE,总压损失有很大程度的降低:在数值计算中,降幅为15.2%;试验测量中为9.7%。陈萍萍 乔渭阳 Karsten LIESNER Robert MEYER 2014航空学报2014,35,11:8
2全面评估蓝耳病对猪场的经济影响显示文摘众所周知,猪蓝耳病(猪繁殖与呼吸综合征,PRRS)不仅对种猪群造成显著的影响,而且对生长育肥猪群也会带来严重的经济损失。猪蓝耳病(猪繁殖与呼吸综合征,PRRS)可称得上是世界上最昂贵的一种猪病,而其对母猪-育肥猪场的实际经济往往容易被低估。当猪场发生蓝耳病时,关于是否以及哪些猪群应该接种疫苗等一些关键的决定可能取决于一些不全面的评估,即只考虑到购买和应用疫苗的成本,却低估了疫苗接种所带来的巨大经济效益。黎先伟 Poul Henning Rathkje Bernd Grosse Liesner 2018兽医导刊2018,0,5:2
