摘要:
为了提高地热资源在温室供热中的利用效率，定性研究了地源热泵地埋管管内强化传热方式,针对横纹管、缩放管和波纹管为研究对象并以光滑管作参照，建立了以水为传热介质的强化传热模型,利用Fluent软件，采用simplec算法和标准k-ε模型，分析了不同的管内结构对管内传热过程的影响，并探讨其强化传热机理，从光滑管和几种强化传热管的传热特性中可得出，在研究范围内，它们的传热效果按优劣依次为横纹管、缩放管、波纹管，为温室供热地埋管的选择提供了可靠的依据。
Abstract:
In order to improve the efficiency of geothermal resources in greenhouse heating，the study on heat transfer enhancement of underground pipe was carried out and a heat exchanger model of heat transfer enhancement was established，which was made for the different tubes with water for heat transfer medium.The influences of different tube structure on heat transfer enhancement were studied by solving the 3D N-S equations and energy equations using the simplec method and the standard k-ε turbulence model in Fluent，and the mechanism of heat-transfer enhancement was discussed.From the heat transfer comparison graph of these three kinds enhanced tubes compared with that of the smooth tube，the order of the strengthening heat transfer effect of these three tubes was transversally corrugated tube，converged-diverging tube and corrugated tube.
