Abstract
The objective of this research is to study the effect of the ring on the behavior of heat transfer to the pot of a KB-5 cooking stove by computational fluid dynamics and experiments. The simulation model was using ANSYS 21 in 3D-model. The effect of the ring on heat transfer behavior to the pot was investigated. Heat transfer to the pot of the stove with ring, being Model B and Model C, was compared with the original stove, the stove without ring (Model A), using total heat flux from simulation and thermal efficiency from experiment. In this study, it was found that the total heat flux from simulation and the thermal efficiency from the experiment of two stoves with rings were better than those of stoves without rings. Model C has the highest total heat flux of 24.40 kW/m2, followed by Model B and Model A with total heat fluxes of 24.42 and 18.32 kW/m2, respectively. Model C and Model B have a total heat flux increase of 24.92 and 14.47%, respectively, compared to Model A. Model C has the highest thermal efficiency of 45.80%, followed by Model B and Model A with thermal efficiency of 42.40 and 39.15%, respectively. Model C and Model B have a thermal efficiency increase of 14.52 and 7.67%, respectively, compared to Model A. Thus, heat transfer to the pot of the stove with a ring (Model C) has the highest performance.
