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。
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.
