Abstract
Although the reduced-order model (ROM) based on residence time distribution (RTD) can predict first-order reactions, high-order reactions require empirical data given the influence of mixing on chemical reactions, and are characterized by the Damköhler number. We attempted to numerically analyze the turbulent reacting flow in a micro-confined impinging jet reactor (CIJR) with a mixing-sensitive reaction system. A ROM framework for the CIJR was built by dividing the reactor space into a well-mixed segregation zone consisting of three reactor cells distinguished by their Damköhler numbers. The volume and pressure drop of the reactor were measured to test the control performance. The ROM was reliable and fast in the dynamic simulation of turbulent flow reactors with competing parallel second-order reactions. Our results suggest that the flow mechanism should be carefully considered when modeling the reactors.
