Experimental and Numerical Investigation of Mode I Fracture Behavior in Magnesium Single Crystals
(2018-04-02)
Magnesium alloys, owing to their low density and high specific strength, are potential candidates for structural applications in automotive and aerospace industry. While considerable research effort has been devoted in ...
Optimal Synthesis of Adjustable Four-Link Planar and Spherical Crank-Rocker Type Mechanisms for Approximate Multi-Path Generation
(2018-04-02)
The well known synthesis problem of obtaining dimensions of a four-link mechanism such that a point on the coupler link traces a desired path has been extensively studied. There are two types of path generation–path specified ...
Coupled Heat Transfer Processes in Enclosed Horizontal Heat Generating Rod Bundles
(2018-03-24)
In a nuclear fuel cask, the heat generating spent fuel rods are packed in a housing and the resulting bundle is placed inside a cask of thick outer shell made of materials like lead or concrete. The cask presents a wide ...
Experimental and Numerical Studies on Phase Shifting in an Inertance Pulse Tube Cryocooler
(2018-06-21)
This work is concerned with the design, development and performance evaluation of an inertance Pulse Tube Cryocooler (PTC). The main components of a PTC are the compressor, regenerator, pulse tube and inertance tube coupled ...
Effect of Semi-Solid Processing on Microstructural Evolution and Mechanical Behavior of Austenitic Stainless Steel
(2018-06-19)
In view of the significant advantages offered by semi-solid processing, such as reduction in number of intermediate processing steps and energy input, and the potential for improving component complexity, it is of paramount ...
Piezoelectric Micromachined Ultrasound Transducers : From Design to Applications
(2018-06-21)
Ultrasonic sensors are well known for various applications such as NDT, ultrasound imaging, and proximity sensing. Conventional ultrasound transducers are bulky, work at notoriously high voltages, and consume significant ...
Experimental Studies on Biodiesel Spray Characteristics : Effects of Evaporation & Nozzle Cavitation
(2018-06-21)
Vegetable oil methyl esters obtained by transesterification of vegetable oils are considered to be suitable alternative fuels for diesel engines. However, higher viscosity, surface tension and boiling temperatures of ...
Studies for Design of Layered Ceramic Armour Inspired by Seashells
(2018-06-26)
Pearly layers in seashells, also known as nacreous layers, are reported to be three orders of magnitude tougher than their primary constituent, aragonite. Their high toughness is attributed to a particular structure of ...
Design and Development of a Three-degree-of-freedom Parallel Manipulator to Track the Sun for Concentrated Solar Power Towers
(2018-05-21)
In concentrated solar power (CSP) stations, large arrays of mirrors which are capable of changing its orientation are used to reflect the incident solar energy to a stationary receiver kept at a distance. Such mirrors are ...
Influence of Hydrodynamic Slip on the Wake Dynamics and Convective Transport in Flow Past a Circular Cylinder
(2018-06-14)
Hydrodynamic slip is known to suppress vorticity production at the solid-fluid boundary in bluff body flows. This suppression combined with the enhanced vorticity convection results in a substantial reduction in the unsteady ...
