Thermal Performance of Flat Plate Collector Using Various Arrangements of Compound Honeycomb

The performance of a flat plate solar collector of 2 m super(2) area and fitted with compound honeycomb cells of different arrangements, was analyzed. The effect of gap thickness above, below, or between honeycomb units was evaluated, using single or double units of honeycomb and bottom gaps of 0,3,...

Summary:The performance of a flat plate solar collector of 2 m super(2) area and fitted with compound honeycomb cells of different arrangements, was analyzed. The effect of gap thickness above, below, or between honeycomb units was evaluated, using single or double units of honeycomb and bottom gaps of 0,3, 8, 14, 22, and 36 mm. The bottom gap was shown to be crucial in terms of heat loss coefficient. The highest efficiency and lowest heat loss coefficient was measured for an arrangement of single honeycomb with a 3 mm bottom gap. A compound honeycomb collector with air gaps of appropriate thickness above and below the single honeycomb unit enhances collector performance substantially.
