CFD Analysis of the First-Stage Rotor and Stator in a Two-Stage Mixed Flow Pump
A commercial computational fluid dynamics (CFD) code is used to compute the flow field within the first-stage rotor and stator of a two-stage mixed flow pump. The code solves the 3D Reynolds-averaged Navier-Stokes equations in rotating and stationary cylindrical coordinate systems for the rotor and...

| description | A commercial computational fluid dynamics (CFD) code is
used to compute the flow field within the first-stage rotor and
stator of a two-stage mixed flow pump. The code solves the 3D
Reynolds-averaged Navier-Stokes equations in rotating and
stationary cylindrical coordinate systems for the rotor and
stator, respectively. Turbulence effects are modeled using a
standard k−ε turbulence model. Stage design
parameters are rotational speed 890 rpm, flow coefficient
φ=0.116, head coefficient ψ=0.094, and specific speed
2.01 (5475 US). Results from the study include velocities, and
static and total pressures for both the rotor and stator.
Comparison is made to measured data for the rotor. The comparisons
in the paper are for circumferentially averaged results and
include axial and tangential velocities, static pressure, and
total pressure profiles. Results of this study show that the
computational results closely match the shapes and magnitudes of
the measured profiles, indicating that CFD can be used to
accurately predict performance. |
