✦ Synopsis

Abstract

The penalty function formulation of the finite element method is described for the analysis of transient incompressible creeping flows. Marker particles are utilized to represent moving free surfaces and to visualize the flow patterns. For determining the movement of markers from element to element, the area coordinate system of the linear triangular element is introduced.

With the method presented, a punch indentation problem and an injection problem for an L‐shaped cavity are solved for Newtonian and power‐law fluids.

A new methodology is proposed for the topology optimization of fluid in Stokes flow. The binary design variable and no-slip condition along the solid-fluid interface are regularized to allow for the use of continuous mathematical programming techniques. The regularization is achieved by treating the
