The steady flow of a cylindrical particle with a circular or elliptic cross section through a narrow channel is investigated on the basis of the Stokes equation with emphasis on effects of its asymmetric location and orientation. Numerical analyses are carried out by use of the finite element method to determine the drag, lift, and torque acting on the particle as well as the velocity of the particle floating freely in the Poiseuille flow. The numerical results are applied to blood flow in capillaries.
