Abstract:
Unsteady
flow field in centrifugal fan due to rotor/stator interaction under
designed condition is studied. The PISO algorithm is applied to solve
the kinetic equations with absolute and relative velocities. Compared
with the experimental data, the numerical method for unsteady flow is
proved to be reliable. Moreover the numerical results illustrate only
unsteady scheme can investigate the flow field properly.
