Shock Dynamics due to Downstream Pressure Perturbations: Idealization of Transonic Unstarted Cascade Flutter
Shock wave unsteadiness is an important phenomenon in high-speed aerodynamics. This
phenomenon is observed in many locations of high-speed vehicles, such as supersonic inlets,
ramjet engines, transonic airfoils, high-speed ...
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 ...
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 ...
Experimental and Numerical Studies on Low Emission Syngas Combustion
The present study concerns experimental and numerical investigation of the combustion of low-calorific value syngas in an optically accessible reverse flow combustion chamber. Several modes of operation are investigated ...
A phenomenological one-dimensional model for elastic ribbons
Ribbons exhibit fascinating buckling-dominated behavior under mechanical loading because of
a unique combination of geometric dimensions. The recent interest in examining engineering
applications of ribbon-like structures ...
Analysis and Design of Organic Rankine Cycle based Power Plants
Solving the world’s energy crisis, and mitigating anthropogenic climate change, requires efficiently harnessing non-polluting renewable energy. Organic Rankine cycle (ORC) can be useful in this regard. ORC is Rankine cycle ...
Studies on Flow Dynamics and Spray Swirl Interactions in Gas Turbine Combustor
Coupling of spray with the coherent structures of a highly turbulent flow has been a long-standing problem especially in the context of liquid fuel delivery systems in gas turbine combustors. The atomizer in a gas turbine ...
Analysis and Modelling of Small Scale Organic Rankine Cycle System with Scroll Expander
In recent years, the growing concern about pollution from fossil fuels has resulted in an increased effort for utilization of low-grade heat sources such as industrial waste heat, solar energy and other renewable sources. ...
Development of Tubular Solar Receiver with Supercritical Carbon Dioxide as Working Fluid
Over the past decade, solar powered supercritical carbon dioxide (s-CO2) based Brayton
cycle has been identified as a promising candidate due to its potentially high cycle efficiency
(50%, for turbine inlet temperatures ...
Direct Estimation of Acoustic Source Characteristics of the Internal Combustion Engine Exhaust System and Analysis of Complex Muffler Configurations
Reduction in noise radiated from the IC engines is needed to meet the ever increasingly stringent noise regulations. The unmuffled exhaust noise of an IC engine is the biggest contributor to the overall engine noise. ...
