D. Yossefi et al., STIMULATION AND IMPLEMENTATION OF LAMINAR-FLOW REACTORS FOR THE STUDYOF COMBUSTION SYSTEMS OF ETHANE, METHANE AND DEBORANE, Fuel, 77(3), 1998, pp. 173-181
A physical model for simulating combustion systems in laminar flow rea
ctors has been developed. The model is one-dimensional and includes tr
ansport phenomena. It is derived from conservation equations and therm
odynamic relations. The present model is an extension of zero-dimensio
nal models which were proposed by others. It enables one to accurately
interpret the chemical time. A numerical program, LIOR, has been deve
loped for solving the governing equations. It has been coupled with bo
th CHEMKIN, an advanced package designed to facilitate simulations of
elementary chemical reactions, and with TRANSPORT, a package capable o
f evaluating the transport property coefficients. The numerical code h
as been validated via the simulation of ethane (C2H6) combustion. The
results were compared to available experimental results. Good agreemen
t was evident. The model has been used to examine methane (CH4) and et
hane combustion in a synthetic atmosphere system where nitrogen is rep
laced as a diluent with carbon dioxide. Special attention is given to
the role of the detailed chemistry in the problem using a scheme conta
ining about 100 elementary reactions. Examination of a set of model pr
oblems show that under such conditions, where there is a large concent
ration of carbon dioxide, the chemistry effects are very important. Th
e typical area of application of this work is sub-sea vehicles and oth
er closed-environment machines. The model also served a study aimed at
elucidating the oxidation mechanism of the energy enriched fuel, debo
rane (B2H6) The results obtained can provide the basis for further inv
estigation of this mechanism. (C) 1998 Elsevier Science Ltd.
