摘要
本文实验研究了流体低流速横向冲刷间谐振动圆管的传热特性,其目的是为流体诱导振动的有效利用提供更多的借鉴。研究结果表明流体绕流振动圆管时,在较低流速下即可获得较好的传热效果。对流换热的增强较少地依赖于流动雷诺数,更多地依赖于振动雷诺数。
Heat transfer properties of the vibrational pipe when fluid passes by it slowly are discussed in this paper. The experimental data can offer favorable references to effective utilization of flow-induced vibration. The result shows that the preferable heat transfer effect can be acquired on the condition of a low flow rate. The heat transfer enhancement relies on the vibrational Reynolds number mostly, not relies on the Reynolds number sensitively.
