| Summary: | The unsteady three dimensional flow simulation around sphere using numerical
simulation computational fluid dynamic for moderate Reynolds Number between 20 ≤ Re ≤ 500 is
presented. The aim of this work is to analyze the flow regimes around sphere and flow separation.
Extensive comparisons were made between the present predicted results and available experimental
and numerical investigations, and showed that they are in close agreement. The results show that
the vortex shedding increases with the Reynolds number. The flow separates early when Reynolds
number increases, therefore the separation angle is found to be smaller when high Reynolds number
is present. |
