Finite analytic numerical method for unsteady two-dimensional Navier- Stokes equations (Q798123)

The main purpose of this paper is to develop a finite analytic (FA) numerical solution for unsteady two dimensional Navier-Stokes equations. The FA method utilizes the analytic solution in a small local element to formulate the algebraic representation of partial differential equations. In this study the combination of linear and exponential functions that satisfy the governing equation is adopted as the boundary function, thereby improving the accuracy of the finite analytic solution. Two flows, one a starting cavity flow and the other a vortex shedding flow behind a rectangular block, are solved by the FA method.
