Numerical Methods for Solving a Premixed Laminar Flame.

Abstract

A splitting-up method and an implicit finite difference method are presented to solve time-dependent, one-dimensional, laminar, premixed flame problems. An example for studying the development of an ozone decomposition flame is calculated. A movable boundary technique is adopted, therefore the grid points can be significantly reduced. Special care is taken to maintain the accuracy of the solution. The results are checked in many ways. All checks show that the present method is satisfactory. (Author)
