涤纶高速纺丝过程非牛顿流体力学模型探讨

Studies on the Non-Newtonian Flow Model of High Speed Spinning Process

本文运用流体力学的基本定律,用Jaumann微商描述Jeffreys流体,研究了高速纺丝过程中的单抽拉伸流动,导出了沿纺程的速度方程:,并初步讨论了方程的解。

Based on the basic law of hydrodynamics, the monoaxially stretching flow in the high process is studied. The Jaumann differential quotient is used to describe the Jeffreys fluid and thevelocity equation along the spinning line is deduced as:, the solution of the equation is alsodiscussed preliminarily.
