Experimental And Analytical Investigations Into Development Of Double-Tuned Expansion Chambers And Extended Concentric Tube Resonators
(2011-07-08)
The performance of an acoustic filter (or muffler) is measured in terms of one of the following parameters: Insertion Loss (IL), Level difference (LD) and Transmission loss (TL). All these three parameters may be evaluated ...
Estimation of Stress Concentration and Stress Intensity Factors by a Semi-Analytical Method
(2018-05-29)
The presence of notches or cracks causes stresses to amplify in nearby regions. This phenomenon is studied by estimating the Stress Concentration Factor (SCF) for notches, and the Stress Intensity Factor (SIF) for cracks. ...
CFD Studies Of Pulse Tube Refrigerators
(2012-12-06)
The performance evaluation and parametric studies of an Inertance Tube Pulse Tube Refrigerator (IPTR) are performed for different length-to-diameter ratios, with the Computational Fluid Dynamics (CFD) package FLUENT. The ...
Role Of Boron On The Evolution Of Microstructure And Texture In Ti-6AL-4V-0.1B Alloy
(2013-06-04)
Titanium and its alloys constitute an important class of materials for aerospace, biomedical, and chemical industries, primarily due to their high specific strength and fracture toughness with good corrosion resistance. ...
Studies On The Isolation And Characterisation Of Bioreagents For The Flotation Of Sphalerite From Galena-Sphalerite System
(2015-01-07)
A gradual depletion of high-grade ores, coupled with the growing demand for mineral commodities across the world has culminated in the increased exploitation of lean-grade ores with complex mineralogy. The mineral processing ...
Tensile Behavior Of Free-Standing Pt-Aluminide (PtAl) Bond Coats
(2016-05-03)
Pt-aluminide (PtAl) coatings form an integral part of thermal barrier coating (TBC) systems that are applied on Ni-based superalloy components operating in the hot sections of gas turbine engines. These coatings serve as ...
Evolution Of Texture And Microstructure In Some NiTi Based Alloys And Their Impact On Shape Memory Behavior
(2015-07-08)
NiTi based shape memory alloys (SMA) cover most of the commercially produced shape memory devices and components. The reversible martensitic transformation between the phases B2 (austenite) and B19′ (martensite) is responsible ...
Effect Of Processing And Test Variables On The Deformation Characteristics Of Tantalum
(2016-11-23)
The dependence of flow stress of body centered cubic metals on variables such as strain rate, temperature, strain and microstructural is a research area of continued interest. Recently, there has been renewed interest in ...
