| 在国内外许多学者对波纹管流动和传热特性进行了一些研究, A.Barba等^([7])用乙二醇作为介质，研究了波节管换热器在中等雷诺数条件下的传热性能和阻力性能； 徐建民等^([8])从管子承受内压的角度出发对波节管承受内压爆破的性能进行了研究；Sparrow 对同样具有多个波纹周期的波纹换热管进行了研究，发现在充发展段波纹通道内的传热比相同条件下的直通道的传热系数提高了2.5倍^([9])Wang.G和Vankas.P对对称波纹通道以及波纹管内部流体的流动与换热进行了数值模拟，指出了流动中存在的自维持振荡可提高热质转换效率^([10]) |

| Researchers from home and abroad have conducted analysis on corrugated pipe in terms of its flow and heat transmission characteristics. A.Barba et al [7] made research on the heat transmission property and resistance property of corrugated pipe heat exchanger under the condition of moderate Reynolds number by adopting ethylene glycol as the medium; Jianming XU et al [8], from the perspective of the bear range of internal pressure, analyzed the corrugated pipes capacity of bearing internal explosion; Sparrow also researched corrugated pipes with the same number of corrugation periods, it found that under the same condition, the heat transmission rate in corrugated pipes was 2.5 times higher than that in straight pipes [9]. Wang.G and Vankas.P conducted numeric simulation of the flow and heat transfer inside the corrugated pipes as well as inside the symmetric corrugated channel, and it showed that the self-sustained oscillation of the flow can the heat transmission efficiency [10]. |
