- In this work, the effect of titanium dioxidewater nanofluid on a flat-plate solar collector’s performance has been studied. To obtain the nanofluid, we blended 2% TiO2 (by mass) with pure water. To maintain the prepared nanofluid suspension’s stability and to suppress the possible flocculation problem, we added 0.2% surface activator (Triton X-100) to the mixture by mass, which was further processed by continuous pulsing for 8 hours in an ultrasonic bath. EN ISO-9806 standard was followed for the experimental procedures. The mentioned process resulted in the formation of the required nanofluid and the comparative results are mentioned in the graphic form. The experiments conducted on a flat-plate solar collector showed 49.68% instantaneous enhancement for TiO2- water nanofluid whereas, for pure water, it was only 36.20%
