| 摘 要： | 依据近壁湍流结构及主要特征,提出三种改变流体传热与流动特性的主动控制模式,即顺流下扫模式、逆流下扫模式和垂直下扫模式.对实施主动控制的矩形槽道中的流体流动与传热特性进行数值模拟,并对三种主动控制模式与流体流动、传热间的相互作用进行分析.数值模拟的结果表明,顺流下扫控制模式可以较好地抑制近壁流体的喷出,改善流体的流动与传...

| Abstract: | Three active control strategies including the control strategy,with downstream and sweep feature,with upstream and sweep feature,with vertical and sweep feature that could change the characteristics of fluid flow and heat transfer are proposed based on the main feature of turbulent structure near wall.The characteristics of flow and heat transfer in a rectangle channel with active control strategy are simulated with numerical method.The interaction law of the three control strategies on fluid flow and heat ... |
