Abstract

Finite element analysis of unsteady flow of two‐dimensional incompressible viscous fluid is presented employing stream function as a field variable. The Galerkin approach is applied in the procedure of discretizing in time. Using trigonometric series as the interpolation function, the non‐linear algebraic simultaneous equation system is derived. Several numerical examples show the adaptability of the formulation.
