| dc.description.abstract | Thermoelectric stove is kind of improved cooking stove, can able to reduce the wastage of energy, reduce fuel consumption. Thermoelectric stoves able to convert partially wasted energy in to useful electrical energy in stove. They are designed and developed to harvest energy for home-made utilization. The utilized energy used for lighting application, phone charging, radios, and other home utilities. Due to essentiality of improving cooking stove to minimize wasted energy, and the limitation access of electrical energy, thermoelectric stove is one option cup up such problems. Design, development and performance evaluation of thermoelectric stove is able to generate energy for the one family members, which live in rural community. The conducted computational fluid dynamics (CFD) in stove and thermoelectric module (TE) improves efficiency of stove and the performance of thermoelectric module (TE) significantly. This research work focused on the development and performance evaluation of thermoelectric stove by computational fluid dynamics (CFD), development of performance evaluation includes; specifying size of stove, optimizing of air gap, and determining of location thermoelectric generator (TEG) in stove. This design and development prime concern is to increase performance of stove and performance of thermoelectric module (TE). In this research, size parameters of stove are (��cham..wall=150mm,ℎ��ℎ����.��������=205mm,ℎ�������� ������ =25mm, ��pot=160mm, R flame =89mm, L flame =25mm),and size parameters of thermoelectric module are:( ��1=326 0C, ��2= 88 0C, ����= 298.9 0C, ����������= ������= 0.056×0.056 ��2, �������� = ������ = 0.04×0.04 ��2).Some tools were used to conduct simulations. Solid work 2019 used to draw solid 3D model for both stove and thermoelectric module. ANSYS 2019 used to conduct CFD simulation heat transfer analysis in stove and for meshing, temperature distribution simulation, numerical temperature distribution. Thermoelectric simulation used to conduct thermoelectric heat transfer analysis, voltage developed ( ������) and Power developed (������). Research results show that 3.133W of electrical power is developed with 27% thermal efficiency of stove. The obtained improved air gap that leading increment of performance of the thermoelectric stove. The results obtained from simulations were discussed in accordance with temperature distribution and power developed per module. | en_US |
