Abstract: In the article, the boundary integral technique is used to solve the hydrodynamic movement of a train of deformable fluid particles in a tube. When a fluid particle is ina tube, the total normal stress difference is not constant and more. this force tends todistend and elongate the particle. We find that the difference between the velocity of a deformable fluid particle and a sphere (with the same radius) increases as the distance between the particles decreases, and that the increase in velocity with L1/a1 is greaterthe capillary number, and this increase becomes less pronounced as radius decreases.
