• The hydrodynamic interaction between two (equal and unequal) sphericalparticles moving in a fluid is investigated by the method of matched asymptoticexpansions in the small Reynolds number (Re). The particles are considered soclose that each lies in the inner region of expansion of the other. The flow isassumed axisymmetric. The drag forces on one of the spheres in the leadingand in the trailing positions of a uniform flow are determined upto the term of0(Re) for an arbitrary separation between the spheres' centers. Results for largeseparation are favourably compared with those reported previously by themethod of reflection and the case of small separation is discussed. For equalspheres, the minimum value of interactive (attractive) force is obtained approxi-mately at the spheres' separation of 3.5.
