4. Orientation and flow modeling in injection molding and extrusion
4.1 Decoupled modeling
We'll consider the example of injection. Only the filling phase is taken into account when calculating orientation.
Most injection simulations are based on thin-film flow approximations, or Hele-Shaw approximations (see article ). Under these conditions, Tucker has shown that the velocity field is not significantly modified by the fibers. On the one hand, we can therefore model the filling of the mold...
