Preparation and investigation of wear and corrosion behaviour of Al 7475/ CSA/Graphite hybrid metal matrix composites Sunil Kumar Reddy Kadaru, M. Kannan, R. Karthikeyan Advances in Materials and Processing Technologies, 2024 The Aluminium Metal Matrix Composites are preferred in automotive and aerospace industries for higher strength to weight ratio, good corrosion resistance, and also for better tribological properties. Aluminium improves its qualities by adding reinforcements like fly ash, silicon carbide, tungsten carbide, boron carbide, and ceramic fired bricks. Stir casting is the most common and cost-effective method for processing and creating metal matrix composites, and it is dependent on the processing parameters, reinforcement, and matrix choices. In this investigation stir casting method was used to prepare composites by using Al7475 alloy with preheated reinforced particles of CSA and Graphite. The successful distribution of reinforcements in the Al7475 matrix was confirmed by SEM images of AMMCs and the improved wear and corrosion resistance of AMMC was revealed by the corresponding test results. At 3% Gr and 30N load, the wear rate reduction is 38.4% at 600 rpm, 50.6% at 800 rpm, and 69.4% at 1000 rpm. The highest corrosion rate reduction is possible with 9 % of graphite in CSA composite is 58 %.
Performance study on the CI engine using LHR and LTC in combination with biodiesel blends , Sarathbabu RT, Kannan M, and Journal of Engineering Research Kuwait, 2022 Currently, the research of a single-cylinder 4-stroke direct injection diesel engine, which was naturally aspired, was used, and two modification methods were used. The first is the low-heat rejection method (LHR), and the second is the low-temperature combustion method (LTC). LHR was introduced into the engine by ceramic coating with alumina, which is applied to engine components such as the piston, cylinder lining, and valves and has a thickness of 300 microns without affecting the dimensions of the engine parts. In the next method, low - temperature combustion (LTC) method is done with EGR technique. And the exhaust gas recirculation setting (EGR) is included in the same setup as that of first method. Since, 15% of an exhaust gas is used in the EGR process. The diesel is blended with 20% of mahua biodiesel and 5% of ethanol as a fuel. After that, the engine performance is tested with conventional fuel when compared with biodiesel as a combined LHR and LTC methods. Finally, the engine output is increased by up to 3.48% as a result of the combination of LHR and LTC. As a result, emission levels could be dramatically decreased, and other results obtained could include a decrease in infrared radiation, resulting in a decrease in specific fuel consumption (SFC), and a substantial improvement in engine efficiency characteristics.
Optimized Production of Biodiesel Using Internet of Things Sensed Temperature with Hybrid Particle Swarm Optimization G. Loganathan, M. Kannan Journal of Chemistry, 2022 Biofuel production offers a non-fossil fuel that can be utilized in modern engines without any redesign. Regardless of receiving rising attention, many researchers have explored microalgae-based biofuel production and found biodiesel production is cost-effective compared to petroleum-centered conventional fuels. The primary reason is that the lipid accumulation of microalgae is possible. An efficient technique is proposed for optimized biodiesel manufacturing with microalgae through an IoT device with the hybrid particle swarm optimization (HPSO) algorithm for elapsing such drawbacks. First, the component of biodiesel is determined. Then, from the components, the temperature value is sensed through the IoT device. Based on the obtained temperature, the reaction parameters are optimized with HPSO to increase productivity and reduce cost. Finally, we observed performance and comparative analysis. The experimental results contrasted with the existent particle swarm optimization (PSO) and genetic algorithm (GA) concerning iteration’s temperature, concentration, production, and fitness. The present HPSO algorithm has differed from the existing PSO and GA concerning IoT sensed temperature and production function. Fitness value and instance concentration are the performance parameters. It varies based on the iteration values. Thus, the proposed optimized biodiesel production is advanced when weighed down with the top-notch methods.
Thermodynamic Investigation of a Modified Compression Ignition Engine Fueled by Diesel-Biodiesel-Ethanol Blends R.T. Sarathbabu, M Lakshmikantha Reddy, M Kannan, R Balaji Defence Science Journal, 2022 The present study contrasts the thermodynamics analysis of modified diesel engines with traditional diesel engines. Thermodynamics study is done by the use of energy and exergy analysis for diesel, B20 (blend of 80 per cent diesel by volume with 20 per cent mahua biodiesel) and LHR modification and LTC 15 per cent EGR fuelled with B20 blend and 5 per cent ethanol with various loads ranging from no load to full load. Implemented two technologies for increasing engine efficiency. One of the primary techniques is the Low Heat Rejection (LHR) concept (or the so-called “Adiabatic” engine) applied. In the engine cylinder, a ceramic layer of Alumina (Al2O3) was used to modify the Low Heat Rejection (LHR). Another technique is Low-temperature combustion (LTC) modes are added by joining the inlet and exhaust pipes through valves to control the exhaust gas at an optimal rate of 15 per cent. The findings of energy and exergy distribution in the engine were compared using optimum alterations with fuel blends such as 20 per cent mahua biodiesel and 5 per cent ethanol. From energy distribution, best shaft power (QBP) (2.8kW) is transformed from heat input observed in the optimum altered engine at full load conditions compared to others. Due to modifications employed in the engine and fuels. Maximum unaccounted energy (QUN) loss in diesel (44 %). And highest thermal efficiency (31.2 %) is revealed in B20E5 (LHR+15 % LTC). From exergy distribution, it noticed that the same trend of energy distribution and at 100 per cent load condition, maximum (12.54kW) in diesel and minimum (8.45 kW) in B20E5 (LHR+15 % LTC) has obtained input availability (Ain).The maximum conversion rate of availability in brake power (Abp) (0.61 kW) in B20 (LHR). Compared to diesel, second law or exergetic efficiency more in B20E5 (LHR+15 % LTC).
