为研究低速机电控喷油器电磁阀流动换热特性,以某型喷油器电磁阀组件作为研究对象。在满足电磁阀力学性能的基础上,建立三维仿真计算模型,采用Fluent对电磁阀组件流固耦合共轭传热分析。结果表明:润滑油进口温度为55.0℃,出口温度为78.7℃,重油进口温度为200℃,出口温度为198.8℃,电磁阀靠近重油附近温度逐渐升高,电磁阀温升受重油的影响较大;电磁阀最高温度为93.42℃,远小于极限温度,换热效果较好,其结构满足工作性能要求。本文通过共轭耦合换热分析,为船用低速机喷油器电磁阀设计提供指导。
To study the hydraulics and heat transfer characteristics of the solenoid valve of the Low-speed diesel engine’s electronic controlled injector, one valve assembly is taken as the research object. One the basis of satisfying the mechanical properties of the solenoid valve, a 3-D model is established and Fluent is used to analyze the heat transfer of fluid-structure interaction coupling of the components. Analysis results shows when the inlet temperature of lubricating oil is 55℃,the outlet is 78.7℃, and the inlet temperature of heavy oil is 200℃, the outlet is 198.8℃. The temperature of valve near the heavy oil increases gradually, and the temperature rise of the solenoid valve is greatly affected by the heavy oil. The maximum temperature of the solenoid valve is 93.42℃,which is far less than the limit temperature.The structure meets the requirements of working performance, the solenoid valve’s heat exchange effect is reasonable. Through the analysis process of conjugate heat transfer, this paper provides guidance for the design of the solenoid valve of the low-speed diesel engine’s electronic controlled injector.
