Abstract
This work intended to build a mathematical model for traditional stoves commonly used in rural areas by means of the thermal network approach. The studied stoves had different shapes as around us, but the pots had the same shape and dimension. The three stoves were made of the same type of material (Aluminium) and operated with firewood. Each system (heating device and the pot) was subdivided into 8 isothermal subvolumes, interconnected to one another by a thermal resistance; each resistance corresponding to a particular type of heat transfer. A differential system of 8 equations governing the heat transfer in the ovens’ configurations was obtained, and the instantaneous thermal efficiency of each stove was estimated. Numerical simulation studies were carried out in order to appreciate the thermal behaviour of the systems. The model predicted the temperature agreement with the physical realities and needed a low computational time. From the comparative study, we concluded that amongst our studied stoves, the best heating device is that with an inverted and truncated cone (configuration 2) and is best for cooking since it reduces fuel consumption and therefore has a positive impact on deforestation.
