In this paper we develop a Component Modal Synthesis (CMS) model reduction technique for incompressible fluid flow. We extend the traditional CMS method, developed primarily for linear elasticity, by constructing a divergence free orthogonal modal basis for the fluid velocity. This allows elimination of the fluid pressure from the equations. For the reduced solution we derive a discrete a posteriori error estimate. The performance of our CMS method and a posteriori error estimate is illustrated in numerical experiments.
