摘要：

The cone and plate flow of an Oldroyd-B fluid in the limit of small gap angle was investigated and regions in De-beta-Re space in which there are either zero, one, or infinitely many steady axisymmetric solutions for the infinite cone and plate problem were found. Closed-form analytic expressions for the leading terms in an asymptotic expansion of a steady axisymmetric solution were obtained. This solution is valid for Re of order unity (i.e. for flows with inertia). The effect of Deborah number De, retardation parameter beta, and Reynolds number Re, on secondary flow is discussed.
