Performance, Emission, and Combustion Evaluation of Chlorella Vulgaris Biodiesel-Diesel Blends in a Compression Ignition Engine
Abstract: This study examines, without modifying the engine, the performance, emissions, and combustion properties of biodiesel blends made from Chlorella vulgaris microalgae in a four-stroke, single-cylinder, water-cooled CI engine. The blends of biodiesel and diesel, designated B10, B20, B30, and B40, were 10%, 20%, 30%, and 40%, respectively. Of these, B20 showed the best efficiency-to-emissions ratio. Although it recorded the lowest brake specific fuel consumption of 0.232 kg/kWh, indicating superior fuel …

Thermal Effects in High-Power Laser Systems: Modeling and Mitigation
Abstract: High-power laser systems are increasingly employed in industrial manufacturing, defense, medical procedures, and scientific research due to their ability to deliver high energy density with excellent spatial coherence. However, the performance and reliability of these systems are significantly influenced by thermal effects arising from optical absorption, non-radiative recombination, and inefficient heat dissipation within laser gain media and optical components. These thermal phenomena lead to adverse effects such as thermal lensing, …

Temperature Control of Heat Exchanger using Sliding Mode Control Law
Abstract: Shell and tube heat exchanger system is widely used in chemical plants as it sustains wide range of temperature and pressure. The main purpose of heat exchanger is to transfer heat from a hot fluid to a cooler fluid, so temperature control of outlet fluid is having prime importance. To control the temperature of outlet fluid of shell and tube heat exchanger, a conventional PID controller can be used. But …

Design and Analysis of Water Spray System for Vertical Storage Vessels-Floating Roof Tank for Industrial Safety
Abstract: Large-scale tank fires are a rare occurrence, but they pose a significant challenge to firefighters, oil companies, and the environment. Two options exist for dealing with such fires: letting them burn out on their own or actively attempting to extinguish them. Water spray systems are an effective method for extinguishing fires or providing a cooling effect, particularly on storage tanks. This study presents a designing and analysis of water spray …

Modeling Galaxy Formation in a Hierarchical Universe: A Fiducial Approach and Comparison with Observational Data
Abstract: We have developed a detailed model to understand how galaxies form in the framework of hierarchical theories of structure formation. Our model accounts for key processes like the formation and merging of dark matter halos, the heating and cooling of gas inside these halos, the regulation of star formation driven by energy from evolving stars and supernovae, galaxy mergers, and the changes in star populations over time. This approach is …

Experimental Investigation of Overall Heat Transfer Coefficientin Drop wise Condensation
Abstract: The experiments are performed to study the heat transfer characteristics over a drop wise condensation. The phenomenon of drop wise condensation is in which the condensate forms into drops rather than covering the entire cooling surface with a continuous film. In drop wise condensation, heat transfer coefficient produced is 2 to 10 times greater than those produced by film wise condensation. Hence drop wise condensation is desirable as it is …

Piezo in Implant Surgery: A Literature Review
Abstract: Dental Implants are Titanium cylinders that are widely used by dentists as prosthesis to replace damaged or lost tooth. The process where the implant locks and attaches itself with the bone is termed as osseointegration. Factors like bone quality and quantity, primary stability of implant, surface characteristics of implant are some of the factors that determine osseointegration of the implant.Acceleration of osseointegration may depend on the removal of negative tissue …

Health Assessment of Oil Immersed Transformer Using Fuzzy Logic
Abstract: A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. Commonly, transformers are used to increase or decrease the voltages of alternating current in electric power applications. Mineral oil treats heart of the transformer, its functions are to insulate, suppress corona and arcing, and to serve as a coolant. The oil helps cool the transformer. Because it also provides part of the electrical …
