Abstract

In the present work thermal and thermohydraulic efficiency analysis of v shape wire rib artificially roughened solar air heater (SAH) has been performed. The present result, different data, plots can be used for the design and analysis for v shape wire rib roughened SAH. The main results and conclusions of present investigation are as follows: Solar air heaters with V-shape roughness geometry with using different diameters wire ribs as roughness elements on the absorber plate are more efficient than conventional or flat plate type of solar air heaters. The highest thermal efficiency obtained for roughened SAH 78.7 % for e/D = 0.032, Re = 19970 and I = 800 W/m2.Thermal or energy efficiency as well as thermohydraulic or effective efficiency of roughened SAHs strongly depends on the operating, geometrical and flow parameters.
