THE ORATICAL ANALYSIS OF FLAT PLATE SOLAR COLLECTOR PLACED IN MOSUL CITY BY USING DIFFERENT ABSORBING MATERIALS AND FLUIDS

Abstract

In this paper, a mathematical model and simulation of flat plate solar collector are developed. The weather data, which used in the calculations of the performance of the collector, is for Mosul city. Detailed energy analyses were carriedout for evaluating the efficiency and useful heat gain of a typical flat plate solar collector under certain operation and design conditions. In this analysis, different fluids and different absorbing materials were used to indicate their effect on the performance of flat plate solar collector. Operating parameters, which considered as variables, are the mass flow rate, the inlet and the outlet temperature difference and the total solar radiation flux. The simulation program had written by using EES (Engineering Equation Solver) software program. The results of this analysis show that the copper and aluminum gives a good efficiency up to (0.6) with value (0.02) of collector performance coefficient whenwater as a working fluid, while the plain carbon steel gives efficiency (0.46)that stated previously because of low heat conductance . The results show also that the copper and the aluminum give the largest useful heat gain extracted from the collector as compared with plain carbon steel. It has been also show that the solar collector efficiency is higher in case of using water as working fluid than that of propylene glycol solution
