they must both be rounded off at the same place before subtracting. 10. The
principal advantage of the integro-differential approach is its ability to con-
fine the numerical computation to the region of viscous flow. 11. The pri-
mary purpose of this work is to demonstrate the applicability of the integro-
differential approach for various types of viscous flow problems. 12. The
purpose of this paper is to describe a numerical method of solution of the
Navier-Stokes equations for time-dependent incompressible flow problems.
