摘要
本文对直肋插入件高温换热管内的层流流动与强化传热进行了数值模拟。获得了恒热流率和变物性条件下的流均分布和温度分布,并考查了流体入口温度、热流率和插入件几何形状对插件管内充分发展的层流流动和传热的影响。
The paper presents the numerical simulation of laminar fluid flow and heat transfer in straight fin insert tube of high temperatutre.On the condition of uniform heat input and for temperature dependent properties,the influences of the fluid inlet temperature,heat flux and geometric parameters on the fluid flow and heat transfer in an insert tube were investigated.
