In this paper, the two-dimensional Stokes flow inside and outside a circular cylinder induced by a pair of line singularities ͑rotlet and stokeslet͒ is studied. Analytical solutions for the flow field are obtained by straightforward application of the Fourier method. The streamline patterns are sketched for a number of special cases where the cylinder is either stationary or rotating about its own axis. In particular, some interesting flow patterns are observed in the parameter space which may
