Water is being used to absorb incident light for use in solar power applications. Adding nanoparticles to water improves the solar collection efficiency. In this paper, a Thermal Analyzer measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluids increased with temperature and nanoparticle concentration....
The thermophysical properties of natural and artificial samples of marble were investigated to determine how the marble would respond to solar irradiation. The thermal conductivity, specific heat and density were all determined experimentally for the marble samples, and the thermal diffusivity was calculated using these properties. It was determined based on the thermal diffusivity values that heat travelled faster through the natural samples than it did through the artificial samples. ...
