- •
The effect of a flat plate on the wake flow characteristics of a sphere was studied.
- •
The vortex separation on the bottom of the sphere is suppressed.
- •
A jet flow under the sphere stretches to the recirculation region.
- •
The small-scale vortex structures concentrate on the near wake region.
