【摘要】 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.更多还原

【Abstract】 A simplified model of the Cinquefoil orifice-baffle supported type heat exchanger has been presented.By using those simplification method and FLUENT program,the heat exchanger was analysed numerically.The required information for knowing condition of fluid flow and heat transfer were obtained.The correspond fitting formudlas by the numerical simulation of different span orifice-baffle were given.These formulas provided the basis for designing exchangers.更多还原
