Flow separation causes significant losses in the kinetic energy of the moving fluid stream that translates into larger pressure loss in the flow field.
For instance, he discovered that, at low non-spinning soccer ball velocities, a large flow separation was visible behind the ball.
Combined blowing from all sides further reduces flow separation and drag.
The simulation result highlighted significant flow separation in the gating system and showed that metal arrived at the gates at different times, which is undesirable.

The efforts have been made to design an annular diffuser for no flow separation [2,5,6], however little success has been achieved.
The work may also reduce excessive noise and vibration due to flow separation.
However care must be taken to ensure that it creates no sudden local increase in divergence angle, otherwise flow separation may be initiated.

Losses associated with flow expansion occur in the diffuser as a result of flow separation and the formation of large flow recirculation zones.
The predictions of difficult effects such as flow separation and heat transfer is much improved, enhancing the utility of most industrial flow simulations.
