摘要：本文以求解微分方程组为手段,得到了此问题的近似解,其中选用Oldroyd三参数模型作为流体的本构方程.其理论结果已经电化学实验数据验证,经拟合发现两者较好地吻合,并且发现粘弹性流体的弹性对传质过程肯定有影响.
In this paper, the mass transfer problem of laminar natural convection for non-Newtonian viscoelastic fluids is studied. The Oldroyd model with three parameters is used as an constitutive equation. Experiments were carried out with an electrochemical method. A comparison between the theoretical results and electrochemical experimental data was made.It was found that apparently asymptotic solutions conformed very well with electrochemical experimental data and the elasticity of viscoelastic fluids had a definite eitect on the process of mass transfer.
