Abstract

In this chapter, a numerical investigation is undertaken to study the coupled catalytic and gas-phase combustion processes in a methane-fueled microreactor with catalytically active Pt walls. Simulations were carried out with the 2-D full elliptic model for both the gas and solid phases. Elementary hetero-/homogeneous chemical reaction schemes were included along with heat conduction in the walls, surface radiation heat transfer, and external heat losses. The main objectives were to investigate the interplay of hetero-/homogeneous combustion, transport, and heat transfer mechanisms in the microreactor and to delineate combustion stability maps in terms of the underlying parameters.
