Thermal Explosion of Oxyhydrogen Gas Initiated by the Wall of a Quartz Reactor
TL;DR: In this paper, a criterion for gas ignition initiated by a heterogeneous reaction, in contrast to criteria for a homogeneous thermal explosion in reactors with an inert wall, was developed to calculate gas ignition in nuclear reactors with a catalytically active wall.

Steps in CH4 oxidation on Pt and Rh surfaces: High‐temperature reactor simulations
TL;DR: In this article, a 19-elementary-step model of adsorption, desorption and surface reaction steps with reaction parameters from the literature or from fits to previous experiments was used to simulate the direct oxidation of CH4 to H2 and CO in O2 and in air at high temperatures over alumina foam monoliths.

Modeling the partial oxidation of methane in a short‐contact‐time reactor
TL;DR: In this paper, a tube wall catalytic reactor was simulated as a model for a single pore of the monolithic catalyst using a 2-D flow field description coupled with detailed reaction mechanisms for surface and gas-phase chemistry.

A model of elementary chemistry and fluid mechanics in the combustion of hydrogen on platinum surfaces
TL;DR: In this paper, the catalyzed combustion of lean hydrogen-oxygen mixtures in a stagnation flow over a platinum surface and in a flat-plate boundary layer is analyzed. But the results of the analysis are limited.
Journal ArticleDOI
Experimental and numerical investigation of the catalytic ignition of mixtures of hydrogen and oxygen on platinum
TL;DR: In this paper, the authors studied catalytic ignition of mixtures of H2 + O2 by measuring and simulating the temporal evolution from the kinetically controlled regime (i.e., prior to ignition) to the state controlled by mass transport after ignition.
