Identifiers: Deflagration.A nonlinear eigenvalue problem in one dimension is formulated. This mathematical problem represents both the steady burning of a monopropellant in one dimension and the laminar propagation of a deflagration wave in a uniform combustible gas. The formulation developed assumes a one-step, reversible, exothermic chemical reaction in an n-component gaseous mixture having arbitrary proportions and a Lewis number of unity. A rigorous analysis of this problem is made, and the following results are among those obtained. Existence and uniqueness of the solution (i.e., eigenvalue plus eigenfunction) to the eigenvalue problem are established. The qualitative dependence of the eigenvalue (or burning rate) upon several of the important parameters is determined. Upper and lower bounds for the eigenvalue are derived, and a convergent, monotone, iterative procedure is developed for calculation of the solution to the eigenvalue problem.
