Does Particle Size in Nanofluid Synthesis Affect Their Performance as Heat Transfer Fluid in Flat Plate Collectors?—An Energy and Exergy Analysis
Abstract
:1. Introduction
2. Materials and Methods
2.1. Mathematical Modeling of the FPC
- The effect of dust on the FPC was neglected.
- The thermal capacitance of the FPC was not considered.
- The front and back of the FPC were assumed to have the same temperature.
- The assumption of a one-dimensional perpendicular to the flow region in terms of the heat transfer was made.
- Consideration was given to the rear insulation’s natural convection with the surrounding air.
- Losses from radiation and convection from the insulation’s bottom and side surfaces were negligible.
- The translucent cover blocked off infrared light. It was assumed that the physical characteristics of materials were unaffected by changes in temperature.
- The insulation materials, absorber, and glass cover were not affected by temperature change.

4. Conclusions
- The maximum energy efficiency measured was 73.8%, which was recorded for the fly ash nanofluid with a nanoparticle size of 11.5 nm.
- The maximum energy efficiency of the 114 nm fly ash nanofluid was 73.5%, which was 0.41% less than the 11.5 nm NPS at a Reynolds number of 2000. At a Reynolds number of 800, the energy efficiencies of 11.5, 30.36, 55.5, 89.3, and 114 nm were 71.3%, 71%, 70.72%, 70.67%, and 70.5%.
- At a Reynolds number of 2000, the fly ash nanofluid with a nanoparticle size of 11.5 nm showed a top heat loss coefficient of 4.78 W/m2K, while the top heat loss coefficient of a NPS of 114 nm was 5.17 W/m2K.
- The numerical analysis measured the least and maximum mean plate temperatures at a Reynolds number of 2000 at 34.21 °C and 34.57 °C, respectively.
- At a higher Reynolds number, the pum** power increased significantly. A maximum pump work of 0.114 W was calculated at a Reynolds number of 2000 for the 11.5 nm fly ash nanofluid.
