On the flow past a sphere at low Reynolds number

The flow of an incompressible, viscous fluid past a sphere is considered for small values of the Reynolds number. In particular the drag is found to be given by \[ D = D_s\{1+{3/8}R+{9/40}R^2(log R+γ + {5/3}log 2 - {323/360})+{27/80}R^3log R+O(R^3)\}, \] where D s is the Stokes drag, R is the Reynolds number and γ is Euler's constant.
