The boundary value of the stream function on a body in a two-dimensional flow fluctuates when the flow is unsteady. The value must be given suitably to the flow when the flow, expressed by stream function and vorticity, is numerically solved by the finite difference method. The authors proposed the method of automatically pursuing the appropriate boundary value of the stream function on a body without using any empirical parameter, as a method of satisfying the single value condition of the pressure term of the equations of motion. This method is successfully applied to the calculation of the uniform shear flow around a rotating circular cylinder. The result of calculation shows that this method is applicable to both the steady and unsteady flows without using any empirical parameter.
