| 摘 要： | 本文利用作者已发展的方法,研究了粘弹性流体在狭缝流及环隙流中壁滑移的影响,文中选用了四参数 oldroyd 模型作为此类流体的本构方程,研究发现当壁滑移现象出现时,其速度分布、体积流量以及压力降均表现异常,因此,可以推断质量和热量传递也将受到影响。

| Abstract: | Employing the method developed by author, in this paper, the influence of wall-slip in a narrow slit and in an annulus has been studied. When slip does occur the velocity profile, volumetric flow rate and pressure drop are very different from those of the nonslip case. All the effects are quantified, as shown in equations (8), (9), (10), (13) and (18). |
