摘要：We investigate theoretically on the basis of the steady Stokes equations
for\na viscous incompressible fluid the flow induced by a Stokeslet located on
the\ncentre axis of two coaxially positioned rigid disks. The Stokeslet is
directed\nalong the centre axis. No-slip boundary conditions are assumed to hold进出口管理

Green's\nfunction in large parts analytically, reducing the spatial evaluation of
the\nflow field to one-dimensional integrations amenable to numerical treatment.
To\nthis end, we formulate the solution of the hydrodynamic problem for the viscous\nflow surrounding the two disks as a mixed-boundary-value problem, which we then\nreduce into a system of four dual integral equations. We show the existence of\nviscous toroidal eddies arising in the
