用于降低湍流临界雷诺数的扰流元件及扰流管

本发明公开了一种用于降低湍流雷诺数的扰流元件及扰流管，所述扰流元件包括至少两条平行设置的支撑杆及多块肋板；所述肋板固定于两个相邻的支撑杆之间，且与所述支撑杆保持一定的角度，各个肋板沿支撑杆的长度方向分散设置；所述支撑杆按照一定的螺旋率Y旋转成多周期的螺旋状，固定于所述支撑杆上的肋板随之旋转成弧形状。本发明通过倾斜肋板的诱导，在流体内产生高强度的纵向涡流，由于涡流旋转方向平行于管轴，提高了管内近壁区与核心流动区的混合程度，破坏了边界层的发展，提高了管壁的热流密度，进而有利于提升传热速率。本发明通过对流体的强化传热，可以降低管内流体的临界湍流雷诺数，进而显著提高管内流体在低雷诺数时的综合传热性能。 The invention discloses a flow disturbing element for reducing critical reynolds number of turbulent flow and a flow disturbing pipe. The flow disturbing element comprises at least two supporting rodswhich are arranged in parallel, and a plurality of rib plates, wherein each rib plate is fixed between every two adjacent supporting rods, and maintains a definite angle with the corresponding supporting rods, and each rib plate is dispersed and arranged in the length direction of the supporting rod; and the supporting rods rotate according to a definite spiral rate Y to form a multi-period helical shape, and the rib plates fixed to the supporting rods rotate along with the supporting rods to form an arc shape.
