Flow without turbulence, i.e., the movement of one layer of fluid past another layer with no eddying between them. See Reynolds Number. Most melt flow, even at high velocities, is laminar. With sudden changes in melt velocity, such as may occur at some extrusion-die entries and at injection-mold gates, laminar flow may be disrupted by Melt Fracture. Also see Jetting.
