| 摘 要： | 通过试验,研究了不同结构的交错肋对换热及流阻特性的影响。试验结果表明:努塞尔数和流阻系数,随着肋宽的增大而都增大,随着肋间距的增大而都减小,随着肋倾角的增大而都增大。综合换热效果为1.3~2.5。

| Abstract: | The effect of heat transfer and flow resistance on different structure of crossed-rib is investigated by experiment.The test results show that the Nusselt Number and flow resistance coefficient are increased with increasing rib width;the Nusselt Number and flow resistance coefficient are decreased with increasing distance between ribs;the Nusselt Number and flow resistance coefficient are increased with increasing angle of rib.The synthetical effect of the heat transfer are about 1.3~2.5. |
