Numerical Simulation of Internal Flow Field in a Mixed-flow Pump

摘要：

Mixed-flow Pump is widely used in agriculture irrigation. The three-dimension interior flow filed of three typical operating conditions in mixed-flow pump impeller is calculated using the amendatory turbulent model of κ-ε and SIMPLEC method. Specially introduce the method of numerical simulation to this type of pump and obtain the interior velocity, turbulent kinetic energy and pressure distributions. The flow impinging in the inlet of impeller is analyzed and positions of cavitations in impeller are observed. The conclusions will be helpful in the future correlation researches on the internal flow of this kind of pump.
