Crack Tip Fields And Mechanisms Of Fracture In Ductile FCC Single Crystals
(2015-01-07)
An understanding of crack tip fields and fracture mechanisms in single crystals can help in developing better polycrystalline alloys and manufacturing processes. To this end, the effects of loading rate, material inertia ...
Multi-Phase Modeling Of Microporosity And Microstructures During Solidification Of Aluminum Alloys
(2014-04-23)
Manufacturing of light-weight materials is associated with several types of casting defects during solidification. Porosity defects are common, especially in aluminum and its alloys, which initiate crack propagation and ...
Studies On Friction Stir Welding Of Precipitation Hardenable Aluminium Alloys
(2010-06-10)
Friction Stir Welding (FSW) is an emerging solid state welding process. It has been a proven method for welding high strength aluminium alloys which were previously not recommended for conventional fusion welding. Since ...
Single-Phase And Multi-Phase Convection During Solidification Of Non-eutectic Binary Solutions
(2014-10-20)
During solidification of non-eutectic alloys, non-isothermal phase change causes dendritic growth of solid front with liquid phase entrapped within the dendritic network producing the mushy region. Solidification causes ...
Studies On Automization And Sprays Of Plant Oil Biofuels Using Laser-Based Diagnostics
(2014-12-12)
Atomization characteristics of liquid fuel sprays control combustion efficiency and emissions in engines. The present work is motivated by the need to study the atomization and spray structure of vegetable oil biofuels for ...
Study Of Stall Flutter Of An Isolated Blade In A Low Reynolds Number Incompressible Flow
(2015-07-08)
Highly-loaded turbomachine blades can stall under off-design conditions. In this regime, the flow can separate close to the leading edge of the blade in a periodic manner that can lead to blade vibrations, commonly referred ...
Thermodynamic Analysis And Simulation Of A Solar Thermal Power System
(2014-05-21)
Solar energy is a virtually inexhaustible energy resource, and thus, has great potential in helping meet many of our future energy requirements. Current technology used for solar energy conversion, however, is not cost ...
Development And Performance Evaluation Of An Indirect Evaporative Air Cooler
(2014-09-09)
Evaporative cooling is an alternative and efficient method of cooling in dry climates. When a liquid evaporates into the surrounding gas, the energy required for the change of phase produces a cooling effect. The wet bulb ...
Microstructure Evolution In Semisolid Processing
(2014-09-09)
In this thesis, we present an experimental and numerical study of globularization during reheating of thixocast billet having non-dendritic microstructure. The process of reheating is an important step in the semisolid ...
Exploration And Assessment of HCCI Strategies for a Multi-Cylinder Heavy-Duty Diesel Engine
(2017-10-17)
Homogeneous Charge Compression Ignition (HCCI) combustion is an alternative combustion mode in which the fuel is homogeneously mixed with air and is auto-ignited by compression. Due to charge homogeneity, this mode is ...
