摘要: 本文用积分变换方法分别给出了二阶流体和Maxwell流体管内不定常流运动方程的解析解.据此可以分析轴向速度和切应力分布与变化特征,为管道工程设计提供理论依据.Abstract: This paper presents analytieal solutions to the partial differential equations for unsteady flow of the second-order fluid and Maxwell fluid in tube by using the integral transform method. It can be used to analyse the behaviour of axial velocity and shear stress for unsteady flow of nun-Newtonian visco-elastie fluids in tube, and to provide a theoretical base for the projection of pipe-line engineering.
