PRESSURE DISTRIBUTION ON SPINNING SPINNERETS

Abstract

A two-dimensional model is used to study the pressure distribution in a chamber of a spinneret system. Darcy's law is adopted for determining the inlet and outlet velocities of the flow. The pressure distribution on the spinneret plate is obtained, and the dead zone, where no nozzle exists, can be optimally determined.
