【摘要】 首先给出了Oldroyd-B模型的稳态解,其次将该模型在稳态解处线性化,通过求稳态解处Jacobi矩阵的特征值,给出了系统稳定的条件,最后采用隐式差分格式进行数值模拟,验证了稳定条件的合理性。更多还原

【Abstract】 Firstly,the steady solution of Oldroyd-B model is given in the paper.And then the system is linearized on the steady-state solution.The stability condition is discussed through the eigenvalue of Jacobi matrix.Finally,a numerical sche-me is designed by using implicit difference method and the reasonableness of the stability condition is test.更多还原
