Commercialization and effective use of biodiesel is still unattained due to its poor cold storage property. Biodiesel produced from waste cooking oil (WCO) using methanol was blended with 0%, 80% and 90% petroleum-based diesel (PBD) fuel and 20 ppm, 30 ppm, 40 ppm and 50 ppm of magnesium oxide (MgO) nanoparticles. The test fuels quality was found to be within limits of the ASTM standards. 30 ppm concentration of MgO nanoparticles showed improvement in cloud point (CP), cold filter plugging point (CFPP) and pour point (PP) of the test fuels. The results showed that the brake specific fuel consumption (BSFC) of B100W30A, B20W30A and B10W30A fuels were 28.2%, 9.48%, and 2.45% higher than the B100, B20 and B10 fuel respectively. PBD showed lower BSFC but higher brake power (BP) and brake thermal efficiency (BTE) when compared to the other test fuels. The BTE and BP of the B100W30A, B20W30A and B10W30A fuels were 4.57% and 1.17% on an average higher than those of B100, B20 and B10 respectively. In general, MgO nanoparticles blended fuel released relatively lesser emissions than B100, B20, B10 and PBD. Combustion analysis of nanoparticles blended fuel was better than other test fuels and comparable with PBD.

Priyadarshini Dash, Jatin Gajjar, A. Anderson, J. Jayaprabakar, G. Senthilkumar, Nivin Joy

Summary: The growth of the aviation industry is driven by the increased consumption of aviation fuel, which contributes significantly to anthropogenic CO2 emissions. In response, there has been a focus on developing renewable aviation fuels as alternatives to petroleum-based fuels. Non-edible oils combined with diesel are preferred for biofuels to meet the growing global demand for edible oils and food crops. This study compares important performance parameters of biodiesel blends from both edible and non-edible sources, including brake thermal efficiency, brake specific fuel consumption, and emission parameters such as carbon monoxide, carbon dioxide, smoke, and nitrogen oxide emissions.

Anish Mariadhas, R. Rishi Kumar, S. V. Puneeth Reddy, P. Bency, J. Jayaprabakar, Nivin Joy, S. K. Sahaya Susmi, V Jayaprakash

Summary: This research investigates the effects of nanofluids on computer cooling microchannel heating devices by enhancing heat dissipation through the addition of nanoparticles. The experiment uses a mixture of 25% Therminol-55 and 75% sprinkling water containing silicon carbide (SiC), titanium oxide (TiO2), and zinc oxide (ZnO) nanoparticles. The results show that the SiC-THERMINOL/SPRINKLING WATER mixture with a concentration of 1.5% and a flow rate of 0.080 kg/s has a 9% lower CPU temperature and a 31% higher heat transfer coefficient compared to the base fluid. SiC-TL/SW also exhibits the highest pressure decrease and pumping power compared to TiO2-TL/SW. A slight increase in pumping power and pressure reduction can be tolerated due to the superior cooling performance of nanofluids.

M. Anish, J. Jayaprabakar, P. Bency, Nivin Joy, V. Jayaprakash, K. Arunkumar, J. Aravind Kumar, T. R. Praveenkumar, Ayman A. Ghfar, M. Rajasimman, Balasubramani Ravindran

Summary: The purpose of this study is to experimentally assess the impact of RCCI on the performance, emissions, and combustion of a CRDI engine. A fuel mix (20% biodiesel, 80% diesel, and a NaOH catalyst) is evaluated using ASTM standards. It is found that increasing injection pressure improves brake thermal efficiency but increases NOx emissions. However, increasing injection rate decreases Specific Fuel Consumption (SFC). CO2 and hydrocarbon emissions, as well as smoke opacity values, increase with increased charge. The resulting mixture can be used in a CI engine with pre-mixed ignition to enhance overall engine performance and combustion characteristics.
