| 摘 要： | 利用数值模拟方法,在不同雷诺数下研究了不同放缩比的三角型通道内周期性充分发展的层流流动和换热特性,分析了放缩比和雷诺数对流动与换热的影响.结果表明,当放缩比越小或越大时,流体都容易产生旋涡;随着雷诺数的增大,流体在各种放缩比通道中的阻力系数都是减小的,而换热速率在不同放缩比时随雷诺数的变化是不同的.

| Abstract: | Periodically fully developed laminar flow and convection heat transfer characteristics in triangular passages with different convergent-divergent ratio were numerically studied.The effects of the convergent-divergent ratio and Reynolds number on the flow and heat transfer performances were analyzed.The results obtained show that eddy forms more easily in lower or higher divergent-convergent ratio.It is also found that the friction coefficient of channels reduces with Reynolds number increasing and variations of the heat transfer rate are different at different Reynolds number. |
