摘要: In this paper the expressions for a kind of new rotlets in Stokes flow are derived. By means of superposition of this new rotlets, the drag moment for rotating double spheres and multiple spheres along the smae axis are presented. It has been demonstrated that drag moment for each sphere is the linear function of its angular velocity.

关键词: orthogonal polynomials, Pade’ approximation, Legendrepolynomials, numerical approxiamtion
