Experimental studies on Soot and Particulate reduction in Heavy Fuel Oil Combustion
Heavy fuel oil (HFO) is extensively used in industrial burners and marine engines. HFO droplet combustion gives rise to carbon particulates generated by pyrolysis, which are called cenospheres. There is a current hypothesis ...
Effects of aerosols and atmospheric boundary layer dynamics on refractive index fluctuations: implications for Free-Space Optical communication
Laser communication through atmospheric channels is an emerging wireless technology, commonly known as Free-Space Optical (FSO) communication. It facilitates unprecedented channel capacity and very large bandwidth, favouring ...
Novel, Robust and Accurate Central Solvers for Real, Dense and Multicomponent Gases
The nonlinear convection terms in the governing equations of inviscid compressible
fluid flows are nontrivial for modelling and numerical simulation. The traditional Riemann
solvers, which are strongly dependent on the ...
Turbulence-Premixed Flame Interactions
The interaction between premixed flames and turbulence is an inherently non-linear phenomenon. Understanding such interactions has profound practical implications towards the development of better combustion devices and ...
Experimental studies on the fracture and fatigue failure processes under direct tension in quasi-brittle materials - Graphite and Concrete
Abstract
Fatigue phenomenon is a gradual, permanent, micro structural change that takes place
in a material due to the application of repeated loading. In the case of quasi-brittle
materials like graphite and concrete, ...
Factors Influencing Contaminant Transport in Vadose Zone of Near Surface Radioactive Waste Disposal Facility
Radioactive waste is generally classified as low and intermediate level waste
(LILW) and high-level waste (HLW), based on their level of radioactivity and the time
taken for decay. The low and intermediate level ...
Experimental Studies on Methanol Sprays for IC Engine Applications
In this work, studies have been conducted on sprays of methanol and its emulsions with diesel towards assessing the potential of methanol as an alternative fuel for IC engines. Methanol can be used in compression ignition ...
Trends and Variability in Terrestrial Carbon Fluxes and Stocks over India in the 20th and 21st centuries: A Multi-model Based Assessment
Terrestrial ecosystems play an important role in the global carbon cycle by naturally taking up carbon from the atmosphere through photosynthesis and storing this carbon as biomass and soil carbon. There exists a strong, ...
Studies on the Mechanisms of Fracture, Evolution of Microcracks and Size Effect in Concrete through Acoustic Emission Analysis
The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ...
Ionic Polymer Metal Composite Actuators for Insect Scale Flapping Wing Micro Air Vehicle
Flapping wing micro air vehicles (MAV) have broad applications such as exploration
in hazardous environment, reconnaissance, search and rescue. Ionic polymer metal
composites (IPMC) have emerged as a promising material ...
