Abstract

This paper presents a CFD approach for modelling of combustion in a cooking stove. The combustion inside a semi-enclosed cook stove has been modelled. The stove is made of fire-brick clay and the cooking pan is an Aluminum square plate. The combustion phenomena inside the stove is modeled using the Eddy-break-up combustion model and the k-ε turbulence model. The flow considered, is due to the buoyancy effect and the spatial variation of species concentrations. Empirical data of a typical cook stove has been used as boundary conditions. Only the flaming mode of combustion has been modelled. Temperature, Velocity and combustion product concentration predictions are presented. The predicted temperature fields have been compared with the measurements.
