Effect of inclination on internal heat and mass transfer of active solar still having conical condensing cover

Abstract

The present paper deals with a photovoltaic thermal-flat plate collector (PVT-FPC) integrated solar still having conical shaped condensing cover. On the basis of basic energy balance equations, analytical expressions for various performance parameters have been derived in the terms of design and climatic parameters. The mathematical computation have been executed on MATLAB for a typical day of March month of New Delhi climate condition. The effect of inclination of condensing cover of active solar still on the internal heat transfer in terms of of convective, radiative and evaporative heat transfer coefficient, and the mass transfer in terms of yield of the proposed system have been studied in details. From the present findings, it is observed that the internal heat transfer coefficient depends significantly on the inclination of condensing cover of the proposed model. Furthermore, it is found that the proposed system produced the maximum yield of 6.79 kg/m2 day at 60° inclination of conical condensing cover.
