- The pressure is set as the inlet condition, of which the total pressure is prescribed. A given mass flow is imposed at the outlet boundary.
- The fluid is aero-fuel with a density of 779 kg/m3. The temperature for all the regions is set as 20℃ and the kinematic viscosity is 1.48 m2/s.
- The rotating domain of the impeller is a stationary domain with a rotating reference frame. The interface between the impeller and the volute is connected by the technique of the frozen rotor method. Moreover, the blade surfaces, hub, and shroud are set as solid walls. They satisfy the non-slip condition.
- The SIMPLE algorithm is used to solve the pressure-velocity coupling equation. The convergence precisions of all residuals are below the criterion of 1 × 10−5.
