SIMULATION OF AIR FLOW RATE AT POINT OF CONTACT WITH A STREAM OF MELTED POLYMERIC MATERIAL

Abstract

This paper presents the research of interaction of air flow and melted material in production of fibrous materials. Correlations for calculation of air flow rate in different cross sections of a stream are acquired. The developed method of calculation of air flow rate at point of contact with stream of the melted polymeric material can be used in construction of blow heads models with a slot nozzle in production of fibrous products from different polymeric materials.
