Performance, Combustion, and Emission Characteristics of CeO2-doped Cottonseed Biodiesel in a Non-road Diesel Engine P V Elumalai, N S Senthur, G Ashwin Prabhu, P Sivamurugan, N. R. Dhineshbabu, Choon Kit Chan, Vikorn Tanaratchat Journal of Environmental Nanotechnology, 2026 The present study investigates the effect of incorporating cerium oxide (CeO2) nanoparticles on the performance, combustion, and emissions of a cottonseed biodiesel–diesel blend in a constant-speed, non-road diesel engine. CeO2 nanoparticles were synthesized using a precipitation–ultrasonic method and introduced into a 30% cottonseed biodiesel blend (CSO30) at three concentrations: 20, 40, and 60 ppm. All experiments were conducted on a single-cylinder, 4-stroke, water-cooled, direct-injection diesel engine at 1500 rpm with loads ranging from 0 to 16 kg. Evaluations were based on key performance parameters, including brake thermal efficiency (BTE) and brake-specific fuel consumption (BSFC), combustion characteristics including in-cylinder pressure and cumulative net heat release rate, and exhaust emissions including CO, HC, NOₓ, and smoke opacity. CSO30 exhibited lower brake thermal efficiency and a higher brake-specific fuel consumption than diesel at full load, due to its lower calorific value and higher viscosity. Adding CeO2 nanoparticles improved combustion quality and fuel conversion efficiency. Among the tested blends, CSO30-N60 (with 60 ppm CeO2 nanoparticles) exhibited optimal performance, achieving a BTE of 30.8% compared to 30.2% for CSO30, while improving BSFC by approximately 13% at full load, thus approaching diesel performance (32% BTE). Emissions analysis showed that CeO2-doped blends significantly reduced regulated exhaust emissions. The CSO30-N60 blend showed reductions of 11.9% in hydrocarbons, 17.7% in nitrogen oxides, and 17% in smoke opacity under full-load conditions compared to diesel. The maximum reduction in carbon monoxide was observed for the CSO30-N20 blend, reaching 43.8%. The findings indicate that CeO2 nanoadditives significantly enhance the combustion efficiency of cottonseed biodiesel blends, achieving performance levels close to diesel while reducing exhaust emissions, making them suitable for non-road diesel engine applications. The addition of CeO2 nanoparticles improved the performance of the cottonseed biodiesel blends, enabling near-diesel performance, while neat diesel still exhibited the highest brake thermal efficiency. Overall, the results demonstrate that CeO2 nanoadditives substantially improve the combustion efficiency of cottonseed biodiesel blends, enabling near-diesel performance while simultaneously reducing exhaust emissions, making them suitable for non-road diesel engine applications.
Effect of thermal conductivity and viscosity of alumina and graphene-based nanofluids for advanced thermal studies , G. D. Gosavi, P. Sivamurugan, , M. I. Shajahan, , J. S. S. Allwin Ebinesar, and Digest Journal of Nanomaterials and Biostructures, 2025 The current study investigates the full development of nanofluids at different volume fractions (0.1 and 0.5 vol.), employing a two-step method, as potential advanced heat transfer fluids (HTF), with pure water (base fluid) and alumina and graphene nano flasks (GPN) as nanoparticles and cetyltrimethylammonium bromide (CTAB) as surfactant. The physicochemical properties of the nanofluid combinations were assessed via X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). Zeta potential analysis revealed an increase of up to +37 mV at 0.1 vol % for alumina/water CTAB nanofluid and +35 mV at 0.5 vol % of Graphene/water CTAB nanofluids. The results demonstrated that alumina and GPN nanofluids exhibited improved thermal conductivity and viscosity. The CTAB GPN/water nanofluid displayed maximum thermal conductivity enhancements of 27.48% and 33.79%, while the CTAB alumina/water nanofluid showed enhancements of 10.6% and 19.81% for 0.1 and 0.5 vol%, respectively. The maximum increment in viscosity were found to be 121.28% and 165.84% for the CTAB GPN/water nanofluid and 110.64% and 111.3% for the CTAB Alumina/water nanofluids at 70 °C, respectively. Consequently, this nanofluid can be regarded as a viable alternative to conventional fluids in high-temperature applications.
Experimental Analysis of Nanofluid Circulation in Automobile Radiators: Thermal Efficiency and Flow Behaviour G. D. Gosavi, P. Sivamurugan, Mohamed Iqbal Shajahan, Bharathiraja Journal of Environmental Nanotechnology, 2025 The heat transfer of coolant advancement through radiators significantly influences the optimization of fuel consumption in automobiles. In order to cool the circulating fluid, which is typically water or a water-based mixture, forced convection heat transfer is employed in automotive radiators. This study experimentally assessed the heat-transfer performance of an automobile radiator by evaluating the thermal performance of a specially prepared nanofluid. The nanofluid was created using a two-step process, involving demineralized water enhanced with graphene (GPN) nanoparticles at concentrations of 0.1 and 0.5 vol. %, along with the addition of GPN to cetyltrimethylammonium bromide (CTAB) surfactant in a 1:0.5 ratio for extended stability at the same concentrations. The experiments varied the liquid-side Reynolds number from 10,000 to 27,000, keeping the radiator inlet liquid at a constant temperature of 60–80 °C. This study thoroughly examined the impact of these variables on the overall heat-transfer coefficient. The experimental results show that the maximum increases in both thermal conductivity ratio and viscosity ratio were 32% and 144% without surfactant, and 33% and 165% with the addition of CTAB surfactant. The maximum average increases in the Nusselt number were 18.55% and 26.49% for the GPN/water nanofluid, and 49.05% and 57.56% for the GPN-CTAB/water nanofluid, respectively. The highest performance evaluation criteria relative to the Reynolds number using the GPN/water nanofluid at concentrations of 0.1 and 0.5 vol. % were recorded as 1.30 and 1.29, while for the GPN-CTAB/water nanofluid, the performance values were 1.14 and 1.10. Furthermore, the findings confirm that incorporating nanoparticles and surfactants into the base fluid results in superior performance compared to using water alone.
