摘      要：An experimental and theoretical study of steam reforming of dimethyl ether was carried out in a processor for fuel cell vehicles to explore the effect of temperature gradient and hydrogen content of the processor.A steady-state,laminar,two-dimensional axi-symmetric model was proposed to investigate the fluid flow,heat transfer and chemical reactions in the dimethyl ether steam reforming processor using porous medium *** numerical model was established with Star-CD program using SIMPLE algorithm and finite volume *** verification of the two-dimensional mathematical model was *** numerical results coincided well with the experimental *** effects of the parameters on the temperature gradient and hydrogen content of the processor were studied using the numerical model.
