| In this research, the effect of air flow its amount and direction, moving toward the flame of gas stove is investigated. The aim of this study is to determine the heat transfer from a hot jet (flame) to a parallel plate (cookware bottom). This is achieved by inserting different barriers, designed to control the air ingress, between the jet and the ambient air. Results showed that installing a solid boundary around the flame causes the thermal efficiency to increase. The major reason for this increase is reduction of convection and radiation losses. In all cases, heat transfer from the barriers to the ambient air is shown to affect the thermal efficiency. Insolating the solid boundary causes to increasing the efficiency as well. It is also shown that the thermal efficiency is substantially improved if the ambient fresh air is directed from the bottom side of the flame. Finally, air pollution tests were conducted to see the effect of air ingress control. Experimental results confirmed no harmful effect on the environment. |
