Abstract:
In order to explore the accuracy of Fluent software in simulating the head loss of long-distance inverted siphon, the water-air two-phase flow VOF method in the computational fluid dynamics software Fluent and a three-dimensional standard k~ε model were used to simulate the head loss of long-distance inverted siphon. The calculations considered wall roughness by setting different roughness simulate head loss of small-trough inverted siphon to obtain the roughness of glass fiber reinforced plastic pipe. The measured and simulated head loss values under large flow conditions were compared, which showed that it is feasible to set the roughness of the long-distance inverted siphon to simulate head loss. However, the effects of mesh discretization on the head loss results need further research.
