Based on the six wafer combustor used in the MIT micro-gas turbine engine

an idea was presented that two-dimensional numerical simulations were performed to investigate the effects of hydrogen/air ratio on the combustion characteristics in a micro combustor when the mass flow rate of the mixture was constant. The CFD model of the micro combustor included hydrogen/air flow path

combustion chamber as well as solid walls used to construct the combustor. The simulation analysis included not only the detailed elemental reactions occurred in the combustion chamber

but also the fluid flow dynamics

heat transfer within the combustor and heat loss to the ambient. Through such systematic numerical analysis

the calculating results are considered to be compatible with the experimental results from the overseas

which may be used as the guideline for micro combustor design.
