Computational study of a novel combined cookstove for developing countries


This paper presents a computational study of a novel biomass-solar combined cookstove for developing countries. A computational fluid dynamics (CFD) study was carried out to understand how the proposed cookstoves perform during combustion. The technique was successfully used for predicting the temperature and the flow velocity distribution within the interior of the stove. The results showed that the flame diffused in the combustion chamber reached the maximum temperature of 1550 K and then decreased as the flue gases flowed upward through the distance from the flame zone to the outlet. Velocity distribution and CO2 concentration predictions are presented. The maximum flow velocity in the combustion was found to be 0.217 m/s. The performance of the stove demonstrated that this cookstove can be a novel alternative for households who have low access to electricity and traditionally depend almost completely on biomass fuels.
