Thermal performance enhancement of the wick-type solar still using titanium dioxide nanoparticles embedded in paraffin wax as a phase change material.

In this study, the performance of the wick-type solar still was investigated using phase change material (PCM) with titanium dioxide nanoparticles as a storage material. Therefore, two solar stills were fabricated one of which was operated with pure PCM and the other one was operated with PCM incorporated with Tio nanoparticles. The use of the nanoparticles was to enhance the thermal conductivity of the PCM and hence improve the productivity and the efficiency of the studied solar still.

Comparative study of three different designs of a hybrid PV/T double-pass finned plate solar air heater.

In this paper, three different designs of a hybrid PV/T double-pass finned plate solar air heater (DPFPSAH) are investigated. The PV module is used to produce electricity needed to run the pump and blow the air into the solar collector. In the first design, the PV module is placed on the absorber plate of the air heater.
