摘要
用换热管内微型液轮机实现换热设备在线、连续、自动防垢除垢及强化传热是一种实用新型专利技术。其中,液轮机的转动性能对在线防垢除垢及强化传热效率有着直接的影响。研究换热管内流场的流动特性对于提高液轮机转动性能具有重要意义。运用大型有限元分析软件ANSYS/FLOTRAN,数值模拟了内置液轮机的换热管内湍流场,结果有助于液轮机的性能分析及优化设计。
Using Miniature Hydraulic Turbine in Heat Exchanger Tube (MHT) to realize fouling prevention on-line and enhance heat transfer is a national patent. The rotating performance of the hydraulic turbine has great effect on fouling prevention and heat transfer enhancing. Studying on the turbulent flow in the heat exchanger tube is significant to improve the rotating performance of the hydraulic turbine. The ANSYS is used for the numerical simulation of the turbulent flow in the heat exchanger tube. The results are useful in the property analysis and optimization of MHT.
