Numerical study on cross-type multi-stream plate-fin heat exchanger

  • 摘要: 借鉴顺逆式板翅式换热器研究成果,分析了交叉式多股流板翅式换热器传热机理,建立了基于有限容积法的多股流板翅式换热器传热数学模型,经过合理假设将翅片间距与单元格尺寸独立,拓展了前人数学模型适用范围.同时,以机载交叉式3股流板翅式换热器为例,对单元格尺寸选取进行了探讨,对同一通道单元格内流体流动横向传热进行了分析,证明了忽略流动横向传热的可行性,从而在保证精度不变条件下提高了计算效率;并在流体变入口参数条件下进行试验,对数值计算方法进行验证,通过与试验数据对比,理论计算误差小于7.9%,证明了数值计算方法的合理性.
