ABSTRACT
The solutions of the Stokes equations in Chapters 3 to 6 have been obtained in cases where the system geometry is simple enough (two-dimensional or axisymmetric) to allow us to find an analytical solution. In many real situations, the flow is three-dimensional and the system geometry is complex. We then seek numerical solutions or approximate analytical solutions by means of regular perturbation analysis (when possible). In all cases, the technique consists of using the linearity of the Stokes equations: we write the solution to the
are that the solution thus obtained is the one!
