In this research, nanofluids containing silver and gold nanoparticles were simulated, using water and ethylene glycol as the base fluid. The simulations were carried out using a modelled rectangular test cell, employing constant heat flux conditions through the ANSYS Fluent software. This study builds upon prior research by extending the comprehension of how nanofluids, particularly those involving silver and gold nanoparticles, can enhance photothermal absorption rates. The primary objective of this paper is to conduct a comparative analysis of the photothermal absorption rates exhibited by the two nanofluids under two simulation cases: (1) a constant heat flux applied to only one side of the wall and (2) a constant heat flux applied to both sides of the wall. The results show that both silver and gold nanofluids have excellent photothermal absorption rate and increase significantly when heat flux is applied to both sides of the wall. A better performance is observed for silver ethylene glycol-based nanofluid. Therefore, for a more photothermal absorption rate, it is recommended that silver ethylene glycol based nanofluid should be used.

In this study, the Structural Equation Modeling (SEM) technique was employed to establish drivers for, and barriers to solar energy use by manufacturing MSME’s in selected districts in Morogoro region. The SEM results revealed three main drivers for manufacturing MSME’s use of solar energy for different purposes like manufacturing MSME’s intention to use solar energy, risk perception on solar energy use, and self-effectiveness perception. Also, the results indicated that there are several factors that hinder manufacturing MSME’s use of solar energy for different operations including the environmental concern (i.e., staff/employers’ concern about air pollution resulted from energy use, and staff/employers’ concern about climate change); solar energy awareness (i.e., experience in previous use of solar energy, and understanding of different types of solar PV which can be used at industry level), and lastly, solar energy generation cost (i.e., the generation of solar energy may cause additional cost, and solar energy requires high initial investment cost).
