Numerical study on the effect of different hole locations in the fan case on the thermal performance inside a gas oven range

Highlights: • A numerical study of a gas oven range was carried out using an actual 3D geometry and ANSYS FLUENT. • A test geometry was developed by referencing a real product. • The flow pattern and temperature distribution inside the oven cavity changed dramatically. • Thermal performance was evaluated based on the average temperature and temperature uniformity. This paper discusses the effect of the hole location in the fan case on the thermal performance of a gas oven range. A computational fluid dynamics (CFD) study was carried out in ANSYS FLUENT. A DO model was used to include the effect of thermal radiation in the oven cavity. A test geometry was developed by referencing a real product, including the oven cavity, external walls, fan cases, fans, and burners. The simulation was validated with experimental data and showed that the maximum difference in temperature is 2.5%, while the difference in average temperature is 0.44%. A total of 15 cases were examined using different hole locations in the fan case. The direction of the velocity vector at the holes was changed by the different hole locations, and the flow pattern and temperature distribution inside the oven cavity also changed dramatically as a result. The thermal performance was evaluated based on the average temperature and temperature uniformity inside the oven cavity.
