supported hole

A simplified model of the Cinquefoil orifice-baffle supported type heat exchanger has been presented.

提出了梅花形孔板支撑换热器壳程的单元简化模型,应用CFD软件FLUENT对换热器进行数值分析,得到流场、温度场的细观信息,通过不同跨距折流板的数值模拟,拟合出相应公式,为梅花形孔板支撑换热器的结构优化设计提供了依据。

The orifice-baffle support type heat exchanger(OSHE)supports tube bundle with circular orifice-baffles instead of conventional segmental baffles.

孔板支撑换热器用整圆形孔板代替传统的弓形折流板来支撑管束,消除了大部分传热死区,并由于小孔射流和扰流作用在较低雷诺数下提高了传热效率。
