The optimum flow channel depth and mass flow rate in 10 different designs of solar air heaters have been obtained. The design variations considered are flat absorber type with and without cover glazings; single, double and triple pass etc. It is found that there exists an optimum mass flow rate...

A detailed theoretical parametric analysis of a corrugated solar air heater with and without cover has been presented. The optimum flow channel depth, at which the maximum heat is available at the lowest collector cost, has been obtained. The effect of collector parameters and operating...

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...
