Abstract This paper reports an experimental investigation on the performance evaluation of a linear solar collector using a hybrid nanofluid of CuO and TiO 2 . The
scanning electron microscope was employed to study the morphology of the nanomaterials. A linear fresnel lens was used to concentrate solar energy on the required
length of the glass tube. The nanofluid was made to flow through the glass tube
and absorb the solar energy. Transmittance spectrum of samples indicated optimum
properties for 0.20% volume concentration of CuO and 0.25% volume concentration of TiO 2 based on which the hybrid nanofluid was prepared. The results indicated
superior thermal and optical properties for the hybrid nanofluid. The absorbance of
the nanofluid was found to increase with the concentration of CuO nanoparticles.
Temperature profile indicated that the hybrid nanofluid could absorb more heat then
water and the base fluid even at lower concentrations. Further, the photo-thermal
conversion rate of the samples was found to increase with the absorptivity of the
nanofluid.
