Dean and O'Neill's solution referred to bi-spherical coordinates for the slow motion of a viscous fluid is extended to the general flow with plane symmetry around two spherical obstacles. In particular, the case of two spheres of equal diameter is discussed in detail. The result is first applied to the fluid motion caused by the spheres moving vertically to their line of centres. The drag and couple if the spheres are prevented to rotate, or the drag and angular velocity if they are free to rotate, experienced by each sphere are numerically evaluated and compared with values calculated from corresponding approximate formulae known before. The application is also attempted to the spheres in laminar shear flow.
