This thesis work is primarily motivated to develop plasma assisted hybrid FSW (P-FSW) process for joining of similar and dissimilar materials and the validation of the experimental results with the development of physics ...
Increasing CO2 emissions in the environment leads to global warming which is an issue of great concern today. This awareness of increase in greenhouse gas emissions has resulted in the development of new technologies which ...
There is an ever increasing demand for materials usable at high temperatures and under extreme environmental conditions. The power generation sectors and aerospace industries are fostering the development of alternative ...
This thesis presents a study on the effects of numerical diffusion in the computation of both inviscid and viscous-compressible flows, and developments of new methods for accurate computation of compressible flows through ...
In the design and analysis of engineering devices, it is essential to have the knowledge of medium properties, initial and/or boundary conditions that yield the desired information which could either be stress/strain fields ...
The present study aimed to investigate the microstructure and mechanical properties of Al-Cu-Zn-Fe-Ti-Mg alloy (≈2219 aluminum alloy) microalloyed with silver (Ag in the range 0–0.1 wt.%) under different thermo-mechanical ...
The diesel engines mainly generate a tremendous quantity of carcinogenic oxides of nitrogen (NOx) and soot. The recently reported works reveal that the conversion of pure diesel mode (PDM) to dual fuel mode (DFM) of engine ...
Shape Memory Alloy wire actuators are very popular for offering large actuation force as well as displacement among other smart materials. The response of a SMA wire actuator is non-linear and hysteretic. In literature, ...
Flexible robotic manipulator systems exhibit many advantages over the conventional robotic systems. However, they have not been favoured in production industries due to their vibration‐control issues. This thesis presents ...
We built prototypes of scissor linkages where it was noticed that angled-plane scissor linkage has significantly smaller lateral sway when compared with parallel-plane scissor linkage. It was further noticed that this ...
The combustion of fossil fuel produces a massive amount of carbon dioxide (CO2), leading to increased global warming. Efforts are required to work on technologies that reduce CO2 emission. Chemical Looping Combustion (CLC) ...
Diesel engines have played an important role in the progress of humankind. They are the most reliable and efficient means of producing power. However, these engines are plagued by high emissions of oxides of nitrogen and ...
First time, the elasticity based accurate analytical solutions are presented for static and free vibration analysis of in-plane functionally graded composite and piezoelectric structures. Modified Hamiltons principle is ...
Rayleigh-Bénard convection (RBC) is one of the classical problems in fluid dynamics, in which a fluid layer is heated from below and cooled from the top. In this thesis, various aspects of turbulent RBC inside a Cartesian ...
In the last few decades considerable attentions have been paid by researchers in extending the concepts of LEFM pertaining to homogenous, isotropic materials to orthotropic composite materials. Stress intensity factor (SIF) ...
Autoclaved Aerated Concrete (AAC) is a light-weight building-construction product of fly ash, sand, water, cement, lime and aluminum powder, which is used globally for brickwork. The available AAC blocks have smooth surfaces, ...
The electromagnetic crimping (EMC) is a high energy, high strain rate, high velocity and green mechanical joining technique. Joining of dissimilar materials was very difficult because their physiochemical properties are ...
The present work consists of numerical studies on flow instabilities in natural circulation boiling systems. An exhustive review of literature has been carried out. boiling systems have been modelled using two different ...
The global energy consumption has been increasing steadily due to the rapid industrialization and improvement in the living standard of the mankind. The predominant part of power is still produced from the fossil fuels. ...
