摘要

摘要: 将压力传感器安装在测点测量几何结构复杂的双旋转盘腔转盘表面的压力分布及盘腔进出口的总压损失.实验结果表明:当湍流参数由0.1变化到0.4时,转盘表面的压力先随旋转雷诺数的增大而减小,之后随旋转雷诺数的增大而增大,并且转变的湍流参数对于两个转盘是不同的.在相同湍流参数下,旋转雷诺数决定了转盘表面的压力分布曲线形状;两个旋转腔的总压损失随湍流参数的增大而增大,随旋转雷诺数的变化规律不同,右旋转腔两个入口到出口的总压损失随旋转雷诺数的变化规律也有差异.

Abstract: Pressure distribution and total pressure loss were measured by fixed transducers on proper positions of dual rotating cavities. The results show that with turbulent flow parameter varying from 0.1 to 0.4, the pressure on rotating disk decrease with the increasing rotational Reynolds number at first, and then increases with the increasing rotational Reynolds number. The critical turbulent flow parameters for these two cavities are different. Under the same turbulent flow parameter, rotational Reynolds number dominates the shape of pressure distribution curves on the rotating disk surfaces. When turbulent flow parameter increases, total pressure losses of two cavities become larger. But when rotational Reynolds number increases under the same turbulent flow parameter, total pressure losses of these two cavities are different.
