✦ Synopsis

For a specific combustion problem involving calculations of several species at equilibrium, it is much simpler to write a special computer program and calculate the concentrations, rather than to use a generalized computer program. To calculate these concentrations, one must solve a set of non-linear algebraic equations. This work describes a procedure in which the Newton-Raphson method and the successive substitution method are combined. It was found that for this type of problem, the quantity of unknowns and the nature of the equations, are such that, by adopting the two procedures simultaneously, a much faster and reliable convergence is achieved. This study also shows what possible species should be considered for these calculations. (~ 1997 Elsevier Science Ltd.
