In this paper, a method of analysis for steady viscous flow past a body in an infinite domain is proposed on a matching method of inner and outer solutions which may be regarded as an extension of the method of superposition proposed by the present authors. Viscous flow under consideration are described by the Navier-Stokes equations and the equation of continuity together with appropriate boundary conditions on the body surface and at infinity. It is, however, difficult to solve this nonlinear boundary value problem in an infinite domain, although the finite-element and finite-difference methods are effective tools for solving the Navier-Stokes equations in a restricted domain. If the far field solutions of the governing equations are given properly, the domain of numerical analysis for the Navier -Stokes equations is reduced to the finite one by the use of the method of matching inner and outer solutions. Assuming that the disturbance caused by an obstacle is small, Oseen linearized the Navier-Stokes equatihe cathodic protection is scarcely valid for retarding the crack growth in salt water.
