| 摘 要： | 换热管内安装微型液轮机是一项新发明的专利技术,可实现换热设备在线、连续、自动防垢除垢及强化传热的效果。为了给实验提供充分的理论依据,基于动量守恒(NS)方程和标准κε紊流模型,采用计算流体动力学(CFD)软件,对换热管内液轮机的三维紊流场进行了数值模拟,并结合实例计算出换热管内流速与液轮机转速和压降的关系数值,数值模拟计算结果与实验测定值基本相符。

| Abstract: | Micro-hydraulic turbine installation in heat exchanger tube is a new patent technique; it can be used for online, continuously and automatically preventing and removing scales and for enhanced heat transfer. A numerical simulation is conducted based on the equation of conservation of momentum (N-S) and standard k- ε turbulent field, the relational numerical values between flow rate and rotation speed and pressure drawdown are calculated in combination with examples, the simulation result is consistent with measured values. |
