| Abstract: | The problem of the uniform viscous flow around a forced oscillating vertical mounted circular cylinder is considered.Based on the incompressible Navier-Stokes equation,with the oscillating frequency equal to the period of the wake of the vortex,both the finite volume method and the PISO algorithm were employed for the numerically simulation.Some comparison to the force coefficient and fluid was made between the static cylinder and the forced oscillating cylinder.A sets of Reynolds number were taken to get the rule of the change of the force coefficient and the fluid around the cylinder. |
| Keywords: | mounted circular cylinder forced oscillation VOF method oscillating frequency Reynolds number |
