摘要:
为了得到弹性管束换热器传热元件的振动参数以及流体诱导振动强化传热规律，对平面弹性管束的固有振动特性及脉动流作用下的弹性管束振动规律进行了研究.首先，利用ANSYS软件建立平面弹性管束有限元模型，并对管束进行模态分析；然后利用FLUENT软件对弹性管束内通入脉动流后的流场进行数值分析.结果表明：弹性管束复杂的三维运动状态提高了其换热和抑垢性能；三棱柱绕流体产生的脉动流速度变化范围为0.4~1.3 m/s，波形明显，因此三棱柱绕流体更适合用于脉动流发生装置；数值计算得到的弹性管束振动频率与实际工况脉动流流体流经弹性管束时产生的频率相一致，为弹性管束换热器在实践使用中提供一定的参考意义.
Abstract:
To obtain vibration parameters of the heat transfer components of the elastic tube bundles heat exchanger and influence of the fluid induced vibration on heat transfer enhancement，the natural vibration characteristics of plane elastic tube bundles and the effects of flow pulsating parameters on the vibration were studied.Firstly,finite element model was established and then modal analysis of the elastic tube bundles was done by ANSYS; secondly,the flow field in elastic tube bundles under pulsating flow was numerically analyzed by FLUENT.The results show that the performance of heat transfer and antifouling was enhanced under the threedimensional complex motion of elastic tube bundles; the velocity of pulsating flow produced by the fluid across a triangular prism ranges from 0.4 to 1.3 m/s with obvious waveform,therefore a triangular prism is more suitable for using as a pulsating flow generator; the calculated frequency is consistent with the actual frequency when the pulsating flow crosses the elastic tube bundles,which provides a technical method for elastic tube bundle heat exchanger in the actual working conditions.
