摘要
Johnson-Segalman(JS)模型的定常解(又称稳态解)代表流体的稳态流动。本文首先讨论稳态模型的多解结构和定常解的准确表达公式,给出了判定JS模型存在三个不同定常解在(,)参数平面上的充分必要条件。其次,采用Crank-Nicolson格式对JS模型进行数值模拟。
Steady solutions of Johnson-Segalman（JS） model present the steady state flow of the fluid.In this paper,the structure of solutions of steady state model is discussed and the accurate formula of steady solutions of JS model is given.Moreover,a condition is given which is necessary and sufficient for three distinct steady solutions in planar（,）to ex-ist.The JS model is simulated by using Crank-Nicolson finite difference method.
