Hydrogen production through dimethyl ether steam reforming is an attractive\noption for mobile applications of hydrogen fuel cells. Hydrogen is a major\ntrend in the future of energy development. It is not only pollution-free,\nbut also has a high energy density. Therefore, research on hydrogen fuel cells\nis particularly important. In this paper, a numerical research on dimethyl\nether steam reforming reaction in a reactor has been presented using a computational\nfluid dynamics. A three-dimensional reactor model developed by\nthe commercial software COMSOL (version 5.2a) was used to simulate the\nreaction characteristics by modifying reforming conditions. The simulation\nresults indicate the temperature distribution, mass distribution, and reveal\nthe dependency of dimethyl ether reforming reaction rate on temperature,\npressure, the length of the reactor. The yield of H2 and conversion of dimethyl\nether with different mass ratios and inlet temperature were examined. The governing equations in the model include conservations of mass, momentum, energy and chemical species.
