This paper proposes a reduced-order model (ROM) for unsteady flows which are triggered by dielectrophoretic (DEP) force-driven convection using the proper orthogonal decomposition (POD). The model equations are nonlinear and time-dependent and usually computationally intensive to approximate. Our results demonstrate the feasibility of the POD approach for both the primal and dual model equations in a scenario that is associated with a real-world flow experiment.
