In order to study the energy characteristics and internal flow field of “S” shaped airfoil bidirectional axial flow pumps, the SST k-ω turbulence model is used to calculate the bidirectional axial flow pump, and the experimental verification is carried out. The results show that the error of numerical calculation of forward and reverse operation is within 5%, and the numerical calculation result is credible. The test results show that the bidirectional axial flow pump has a design flow rate of Q = 368 L/s, head H = 3.767 m, and an efficiency of η = 80.37%. In reverse operation, the flow of the bidirectional axial flow pump under design condition Q = 316 L/s, head H = 3.658 m, efficiency η = 70.37%. The flow of forward operation is about 15% larger than that of reverse operation under design working condition, the design head is about 3.70 m, and the efficiency of design working condition is about 10% higher than that of reverse operation. The numerical calculation results show that under the forward design condition (Q = 368 L/s), the hydraulic loss accounts for 6.22%, and under the reverse design condition (Q = 316 L/s), the hydraulic loss accounts for 11.81%, with a difference of about 6%. The uniformity of impeller inlet flow rate under the forward operation is about 12% higher than that in the reverse operation. In forward and reverse operation, with the increase of flow, the outlet streamline, the outlet total pressure distribution, the uniformity of impeller inlet velocity, and the vortex in the impeller domain are improved, and the forward direction is better than the reverse direction. The research results of this paper can provide a reference for the research and optimal design of the bidirectional axial flow pump. View Full-Text
