Experimental study about thermal resistance and heat transfer analysis regarding air gap between two glasses on window for the domestic use

ABSTRACT
In this experimental study mainly focused the thermal property such as thermal resistance and heat transfer analysis for the air gap variations provided in between two glasses on window for the domestic purposes. Easily available surrounding air considered as the experimental mater because of its arrangements. Thermal resistance of inside, outside and glasses (both glasses have same thermal conductivity such as 0.78 W/m K) all are maintained as constant throughout the investigation. But only air gap distance increased from 2mm to 14 mm with gradual increase focused. The thermal conductivity of air considered as 0.026 W/m K. Thermal resistance and heat transfer impact with respect to the air gap between glasses were identify with the help of graphical representations.
