Optimization of fin and tube parameters in a flat-plate collector
A theoretical investigation for optimizing collector-cost effectiveness is carried out by considering various tube diameters, materials, tube spacing, fin materials, and thicknesses for black and other paints. The bond conductance is taken into account for various joining techniques. Various tube geometries are considered and the convective heat-transfer coefficients are calculated. The pressure drops are calculated with allowance for the friction factor due to the skin effect. Since the friction factor for bends and fittings is negligibly small in the laminar flow regime, the pressure drop is calculated for skin friction alone. Efficiency and costs are computed to determine an optimal system.
