Abstract

Solar collector is a device that increases temperature of fluids with transmission of solar energy to working fluid. Using base fluids such as water and ethylene glycol causes low efficiency in these devices, Due to low thermal properties. Recent researches showed that nanofluids have wide use as working fluid of solar collectors, because of special thermophysical and thermo-optical properties. In this paper effects of new parameters for instance, thickness of glass and insulation and use of black internal surface instead of reflective internal surface, have been investigated on efficiency of DASC in different working fluids. NUMERICAL SIMULATION used in this paper. Simulated nanofluids have 0, 0.005% and 0.01% volume fractions. The efficiency in different volume fractions decrease between 3.22 to 7.36% by increasing thickness of glass. Changing thickness of insulation improved the efficiency of collector by1.53- 2.95% in the base fluid and nanofluid. Finally, results showed that use of black internal surface specially in low volume fraction has significant effect in efficiency; Note that efficiency improved by 16.11% in the base fluid.
