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]. |
