Bubble and conical forms of vortex breakdown in swirling jets
The present study focusses on vortex breakdown (VB), which occurs in axially convected
swirling
flows and is characterized by the development of an internal stagnation point
and regions of reverse
flow. VB has been ...
Mass Transport in Cu-Interlayer-Si Systems under Various Thermo-Electro-Mechanical Excursions
This work falls in general area of the electro-thermo-mechanical driven mass transport in Cu-Si systems, which often finds relevance while accessing reliability issues pertaining to thin film interconnects in microelectronic ...
Methodologies for Risk Assessment of Landslides Induced by Rainfall and Earthquake
Landslide is one of the greatest natural catastrophes and poses a major threat to lives and property worldwide. As development expands into unstable hill areas under the pressure of increasing population and urbanisation, ...
Role of in-phase octahedral tilt influencing structure and properties in Na0.5Bi0.5TiO3 - based piezoceramics
High performance perovskite (ABO3) based piezoceramics are used as actuators, pressure sensors, and transducers in wide-ranging applications spanning sectors like health, space, defence and automobiles. For over four ...
Role of Physico-chemical Processes And Micro-structural Features in Influencing Moisture Loss and Engineering Properties Of Compacted Residual Soils Exposed To Environmental Relative Humidity
The moisture content of residual soils above the water table, and near ground
surface (≤ 6 m) is influenced by the environmental relative humidity (RH). The focus of
this thesis is to examine the physico-chemical and ...
Supporting Environmentally-benign Design at Conceptual Stage
An ‘environmentally-benign design’ is defined as that which causes little or no harm to the natural environment and may
be achieved by reducing the environmental impact of the design solutions conceptualised, to be ...
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. ...
Real Time Solutions to Aerospace Optimal Control Problems
A real-time autonomous trajectory generation methodology for aerospace vehicles using
pseudo-spectral based global collocation methods is presented in this thesis. The proposed
method is formulated in a manner whereby ...
Co-continuous microstructures through spinodal decomposition in ternary systems: A phase field study
We have studied spinodal decomposition which leads to a three-phase microstructure in ternary
alloys using computer simulations based on the ternary Cahn-Hilliard equations. All the alloys
we have studied are in the same ...
Response of Plain and Reinforced Concrete Elements to Various Mechanical Loads
Reinforced concrete (RC) is being used for a wide range of structural applications. In order to design safe and economical RC structural elements it is necessary to analyse these elements accounting for the realistic ...
