Presented a three-dimensional mathematical model of flow and heat transfer in the metering auger unit with an adapter. The effect of geometrical parameters on the processes temlomassoobmena adapter for flow of the polymer melt. In mathematical models have been considered the material of the viscosity characteristics of the temperature and shear rate, the channel adapter considered in three-dimensional spatial reference system, without the unfolding plane, and channel without using the reversed principle of motion.

mathematical model, screw, polymer dosing area, adapter melting.
