abstract

A multibody transportation system that moves with fluid inside a small-diameter tube has been studied by a lot of researchers. It is expected to be developed for future engineering applications such as a micro machine that transports medicines to a certain part of a body. This paper deals with the flow characteristics around a single rigid body and transient motion of the body when a body is influenced by pressure force from upstream. The model considered a body smaller than a diameter of a tube so that the force on the body can be numerically and analytically estimated as viscous friction force. It was assumed that the flow is axisymmetric, laminar and taken to be Newtonian and incompressible. It was obtained that the axial component of the fluid velocity decreases and pressure increases near the body like stagnation flow. Moreover, the pressure rapidly increases behind the body and decreases in front of the body with increasing diameter of the body.
