Smoldering Combustion - Essay ExampleFor instance, a fairy produces char due to the chemical contents, but the combustion is influenced by physical factors. This implies that the physical elements spur the chemical reactions through the oxidization process that attack the bum contents.The article also tackles the post-initiation features of burning. This comprises of various smoldering models, such as one and two-dimensional smolder models. However, oxygen controls the entire combustion process and this depends on the regulate and degree of the reaction. One-dimensional smolder spreads based on the oxygen diffusion, either upwards or outwards from the layer of fuel particles (Ohlemiller 2-220). This model is restricted by reverse and forward propagation approaches. The combustion reaction is sometimes instigated by self-sustained processes. In this regard, self-sustained smolder propagation is prevalent by the oxidation kinetics of a solid. Reverse propagation is when oxygen dif fuses to the reaction region from the external surface of the fuel layer. Forward propagation also affects the one-dimensional smolder in which oxygen flows in the similar direction as the movement of the smolder front (Ohlemiller
