Heat Transfer Enhancement in Louvered Fin Flat Tube Radiator Using Hybrid Nanofluids
This research explores the potential of hybrid nanofluids to improve the thermal efficiency of a car’s louvered fin flat-tube radiator. Hybrid nanofluids were prepared by combining distilled water with a 0.1% vol. concentration of Si and MWCNT nanoparticles, using different ratios of nanoparticles: 80:20, 50:50, and 20:80. The experimental analysis focused on examining the heat-transfer performance of the radiator. The results clearly demonstrated a significant improvement in the radiator’s thermal performance when using hybrid nanofluids. These nanofluids effectively enhanced the rate and coefficient of heat transfer. Notably, an increase of 15.6% in the Nusselt number was observed with the Si–MWCNT 20:80 water containing a 0.1% volumetric concentration of nanoparticles. Overall, the findings highlight the promising application of hybrid nanofluids in boosting the thermal efficacy of car radiators.- 19 September 2023

Experimental Investigation of Impact of Cool Roof Coating on Bifacial and Monofacial Photovoltaic Modules
Cool roof coatings are being applied on rooftops to reflect solar irradiance back into the atmosphere. Bifacial photovoltaic modules can receive solar irradiance from the front and rear side. The purpose of this study is to investigate the impact of reflected irradiance caused by cool roof coating (CRC) on the performance of bifacial photovoltaic (bPV) modules and monofacial photovoltaic (mPV) modules. According to the experiments, cool roof coating is an efficient way to increase the output and efficiency of solar modules. Experimental results show that for cool roof coating based on TiO2 and FC resin with an average albedo of 0.63, the peak power output of the bifacial photovoltaic module is increased by 3.29% and its highest peak power efficiency is 18.1%. A peak power bifacial gain of 15.6% is seen. Due to a 1.3 °C decrease in temperature, the monofacial photovoltaic module power output also increased by 0.24%.
