the result indicated that there is a typical recirculation region in rectangular sedimentation tank.
利用水力模型进行示蹤试验,结果表明在平流式二沉池中存在明显的回流区。
sgs turbulent kinetic energy and sgs turbulent dissipation decrease with the flow developing spatially and both are weaker in the recirculation region than in other flow regions.
研究表明,亚格子尺度湍动能和亚格子湍耗散随着流动在空间的发展而呈现减弱趋势,回流区内亚格子湍动能和耗散较弱;
the reynolds stress in the recirculation region is due to the turbulence structure, not the local mean velocity gradient.
回流区的平均速度场分布与紊流度无关,回流的雷诺剪应力大小与当地平均速度无关,回流不是来自很远的下游。
at this recirculation region the shear stresses are low and oscillate;
该回流区的壁面剪应力数值较低,并且壁面剪应力是交变的。
the flame is mainly located in the recirculation region where the flame is stabilized.
燃烧火焰基本上位于回流区所在的位置,火焰在回流区被稳定。
