Analysis of Transcritical CO2 and CO2+ Propane Mixtures for Tropical Cooling Applications
The increasing global average ambient temperatures coupled with stringent environmental regulations has turned the focus on natural working fluids such as Carbon dioxide (CO2), and hydrocarbons for use in the refrigeration ... -
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. ... -
Efficient Learning of Koopman Structures for Model-Based Control of Nonlinear Robotic Systems
Identification of the dynamics of a complex robotic system accurately from first principles is challenging and often infeasible. Simplifying assumptions commonly made in modeling such systems often restrict their scope and ... -
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 ... -
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 ... -
Flow and Forces on Rigid and Flexible Plates in Unsteady Rotational Motion
The swimming motion of fishes have long fascinated scientists and engineers. Over the past few decades, researchers have studied physical models mimicking the tail beat of fishes in an effort to extract key physical ... -
Multi-linear Disassembly Path Determination: A Geometric Approach
This thesis presents a geometric approach for determining the orientation-preserving disassembly paths of polyhedral assembly components. Exact disassembly path determination of the components is essential because the ... -
New Mechanical Methods to Join Sheets in Lap and Butt Configuration and Analytical Model to Predict and Improve Clinching Joint Strength
Mechanical joining of sheets has many advantages over other joining methods in terms of wide variety combination of similar, dissimilar and non-metallic material sheet joining. In conventional SPR joining, the rivet and ... -
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this emergence has been ... -
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 ... -
Studies on Metal Hydride Based Multifunctional Coupled Thermal Battery Systems
Thermal energy storage systems (TESS) based on chemisorption/thermochemical reactions have several advantages over conventional thermal storage systems based on sensible and latent heat. The advantages include high energy ... -
Vaned Diffuser Effect on Centrifugal Compressor Performance and Stall
A centrifugal compressor is a mechanical device that helps to achieve higher pressure ratios at lower mass flow rates. It is used in many applications such as turbochargers, cruise missiles, and turbojet engines where ...
