ABSTRACT: Unsteady flows in a channel with oblique
plates have been numerically investigated. The oblique plates as disturbance
promoters are installed at the upper wall. Unsteady characteristics are examined
for Re = 350 and the plate angles of a = 60。-
120。. The flow fields represent three-dimensional features variously as the
plate angle varies. From frequency analysis, it is noted that the disturbed
flow by the oblique plates has peculiar unsteady modes. As the flow is more unstable,
multiple frequencies are appeared.
