• Transient aerodynamic characteristics of the flows around bodies of parachute-like configuration are numerically analysed from solution of the Navier-Stokes equations. The computational method is mainly based upon combination of effective and efficient techniques recently developed in the field of computational fluid mechanics. The results show that the flow behavior around a mouth plays a key role in determining the maximum peak drag acting of the parachute-like body in the starting period from the rest and also a vent is effective in controlling the starting peak of the drag.
