Hydrodynamic phenomena during molding in a rotary mold

2 HYDRODYNAMIC PHENOMENA DURING MOLDING IN A ROTARY MOLD [Pg.139]

The geometrical characteristics of the flow field for free movement of a Newtonian liquid on the surface of the rotating cylinder with a horizontal axis is shown in Fig. 4.21 (after179). In [Pg.139]

2 - movable filling device 3 - coating being molded 4 - bearings. [Pg.140]

Here vr is the radial speed of the liquid, vo is circumferential velocity of the liquid, to is the velocity of rotation of the cylinder. [Pg.140]

The solution of the hydrodynamic problem of boundary layer flow, excluding the effects of surface tension, requires simplification of the formulation this is achieved by introducing the flow function t /. Then the transition to a system of differential equations written for a new coordinate system (turn angle and flow function) can be made, and we can find the form of the free surface [Pg.140]
