Perhaps the simplest type of nontrivial, fluid dynamical problem which is used to test various types of models and numerical methods is the two-dimensional cavity flow problem. This problem is formulated as follows: Determine the motion of a fluid which fills a square basin, or cavity, when the upper side, or lid, is in uniform horizontal motion. In this chapter we will formulate and explore a particle model for the cavity problem.
