The steady-state incompressible laminar flow in a semi-infinite circular pipe with uniform injection or suction through the porous wall has been investigated. The present analysis simulates also the flow field produced by the burning of inner surface of cyindrical grain in a solid rocket motor. A similar solution of fully non-linear form of the Navier-Stokes equation is calculated numerically. The properties of flow such as velocity components are obtained as functions of injection parameter R=aV/ν. The region near the closed end has been analyzed numerically by means of the finite difference method, and the results is used to inspect the similar solution. It is found that the flow is not similar near the closed end, and that the effect of viscosity of solid end has been confined to the narrow region of x/a<2.
