Multi-scale reduced order models for transient simulation of multi-layered monolith reactors

We develop and use a multi-scale averaging technique based on the Lyapunov-Schmidt (L-S) reduction method to obtain reduced order models for monolith reactors with multiple washcoat layers. These models are expressed in terms of phase-averaged concentration modes and inter as well as intra-phase (dispersion) fluxes. The various fluxes are determined by the local equations that are linear in the concentration modes and fluxes. It is shown that...
