为了探索采用Fluent 软件模拟研究长距离倒虹吸水头损失的准确性，利用计算流体力学软件Fluent 的水气两相流VOF法，采用三维标准k- E模型对长距离倒虹吸水头损失进行模拟计算。计算中考虑壁面粗糙程度，设置不同的粗糙度模拟小洼槽倒虹吸水头损失，从而得到玻璃钢管材粗糙度范围。对比较大流量下水头损失的模拟值与实测值，表明通过设置粗糙度模拟长距离倒虹吸水头损失的方法可行，但网格划分对结果的影响大小还需进一步研究。

In order to explore the accuracy of Fluentsoftware in simulating the head loss of long-distance inverted siphon, the wa-ter-air two-phase flowVOF method in the computational fluid dynamics software Fluentand a three-dimensional standard k~Emodel were used to simulate the head loss of long-distance inverted siphon. The calculations considered wall roughness by set-ting differentroughness simulate head loss of smal-trough inverted siphon to obtain the roughness of glass fiber reinforced plastic pipe. The measured and simulated head loss values under large flowconditions were compared, which showed thatitis feasible to setthe roughness of the long-distance inverted siphon to simulate head loss. However, the effects of mesh discretiza-tion on the head loss results need further research.
