Abstract

The finite nature of fossil fuels and their adverse effects on the environment have forced mankind to look for alternate energy sources. Solar energy is one of them, and Pakistan has immense potential. This paper specifically focuses on achieving these purposes by using compound parabolic collectors. They are non-tracking and are used for low to medium temperature ranges. To achieve thermosiphoning, nanofluids, which have a high heat transfer rate, are used. Flow rates and outlet temperatures are obtained, by experimentation and by a numerical analysis with water and nanofluids (Fe2O3 and Al2O3). The maximum numerical flow rate achieved was 9.3 mL/s with Fe2O3. The maximum flow rate achieved in the outdoor setup was 10.78 mL/s. Numerical and experimental results were validated with previous research with some deviation. The use of nanofluids and thermosiphoning can greatly enhance the performance of our system and reduce the mechanical work of a pump in a hybrid system.
