Subject: extrudate swell Пожалуйста, помогите перевести.Выражение встречается в следующем контексте:In this Section we present a simulation of the planar Newtonian extrudate-swell problem: the extrusion of a viscous fluid through a die into an inert medium. This is a well-known free surface problem: at low Reynolds numbers, the fluid swells as it comes out of the die. Implicit formulations are capable of accurately predicting the swelling ratio of a Newtonian jet, and should therefore provide a firm numerical foundation for extension to viscoelastic jets where the swelling ratio is of considerable industrial importance.
Extrusion is one of the major processing methods in the polymer industry. Polymeric materials when extruded are commonly found to have larger dimensions than the die. This phenomenon is known as die-swell or extrudate-swell. Due to its importance in industrial applications, this phenomenon has been investigated by many researchers through experiments and numerical simulations.>Заранее спасибо
