Fig. 4 Solar rays impinging
on glass tube
Figure 4 shows the photograph of the solar rays impinging along a line on the
glass tube.
4 Conclusions
Thermal properties of heat transfer fluid comprising of CuO–TiO 2 nanoparticles
with ethylene glycol base fluid with a range of volumetric concentrations (0.020–
0.2 vol%) have been studied experimentally. The solar radiation was concentrated
along the length of the tube by means of a Fresnel lens. The result revealed that
the temperature of the heat transfer fluid increased even at lower concentration of
nanoparticles. The photo-thermal conversion rate was found to increase with the
absorptivity of nanofluid.
