Combustion is a widely occurring phenomenon in nature (e.g., wildfires) and is extensively used in both everyday life and industrial applications. The ability to predict and control combustion processes is crucial, as it enables desired outcomes in industrial systems and helps mitigate destructive effects caused by spontaneous fires. The primary objective of the present study is to formulate a model for the combustion process. Specifically, we propose an analytical approach to examine diffusion combustion. In our analysis, we focus on combustion scenarios where the flame emerges through an opening. Using this model, we investigate various combustion regimes. An additional aim of this paper is to develop and validate an analytical method for the study of the described combustion behavior.
