Abstract
Numerical simulation is carried out to investigate 3‐D complex flow and performance characteristics of double‐suction centrifugal pump by using a CFX code. Double‐section centrifugal pump consisted of six blades impeller and shroud ring. Rotating speed of closed type impeller is 3000 rpm. Finite‐volume method with structured mesh and k‐ω Shear Stress Transport turbulence model was used to guaranty more accurate prediction of turbulent flow in the pump impeller. Total head, power and overall efficiency were calculated according to the variation of flow rate to obtain performance characteristics of two types of pump. From the results, impeller having smooth curve along the shroud line obtained good performance. Complicated internal flow phenomena through impellers such as flow separation, pressure loss, flow unsteadiness and performance are investigated and discussed.
