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 ... -
Characterization Of Al-Si Alloy Engine Bores For Tribological Studies
(2013-06-06)Aluminum - Silicon alloys are recognized as appropriate materials for high performance cast components used in transportation powertrain applications. A combination of excellent wear resistance, good thermal conductivity ... -
Design And Development Of An Improved Anti-Lock Braking System For Two-Wheelers
(2011-07-12)In today’s fast moving world, automobiles are facing challenges in terms of having to survive road accidents, increasing traffic, bad road-conditions and high/express ways. Brake systems play a vital role in controlling ... -
Effect Of Squeeze Film Flow On Dynamic Response Of MEMS Structures With Restrictive Flow Boundary Conditions
(2011-07-08)There are many ways in which the surrounding media, such as air between an oscillating MEMS structure and a fixed substrate, can affect the dynamic response of a MEMS transducer. Some of these effects involve dissipation ... -
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 ... -
Experimental And Numerical Studies On Flame Stability And Optimization Of A Compact Trapped Vortex Combustor
(2013-03-27)A new Trapped Vortex Combustor (TVC) concept has been studied for applications such as those in Unmanned Aerial Vehicles (UAVs) as it offers potential for superior flame stability and low pressure loss. Flame stability is ... -
Force Measurements On Rigid And Flexible Oscillating Foils
(2013-10-04)In the present work, we experimentally study thrust generation from sinusoidally pitched rigid and flexible foils immersed in a uniform flow. The flexible foils are made by attaching a flexible flap of known flexural ... -
Measurement And Analysis Of Friction Induced By A Cutting Operation Lubricated By Oil In Water Emulsion
(2013-09-05)The lubricants that are applied during metal cutting acts on the interface between the tool and the nascent surfaces generated by the cutting process. Dispersions of oil in water made using suitable emulsifier(s) are used ... -
Modeling Of Transport Phenomena In Arteries
(2013-05-23)Atherosclerosis is an arterial disease that occurs due to the build-up of lipids, cholesterol and other substances in the arterial wall, collectively called plaque, leading to narrowing of the vessel lumen and, in time, ... -
Nanotribology Of Emulsified Lubricants
(2011-07-01)In case of metalworking operations, the purpose of lubrication is served by a complex mixture of two or more phases, these mixtures are known as metalworking fluids (MWFs). For many decades oil-in-water emulsions have been ... -
Numerical Simulations Of Two-Phase Reacting Flow In A Cavity Combustor
(2013-05-28)In the present work, two phase reacting flow in a single cavity Trapped Vortex Combustor (TVC) is studied at atmospheric conditions. KIVA-3V, numerical program for simulating three dimensional compressible reacting flows ... -
Simple Models For The Mean And Transient Intertropical Convergence Zone And Its Northward Migration
(2011-11-16)Satellite data have shown that east-west oriented cloud bands, known as Intertropical convergence zone (ITCZ), propagate eastwards along the equator throughout the year and northwards during boreal summer on intraseasonal ... -
Tribology Of An Etched Near-Eutectic Aluminium-Silicon Alloy Sliding Against A Steel Counterface
(2013-05-01)Lightweight aluminium-silicon alloy is an attractive material for making engine cylinders in automobiles. It imparts good power to weight ratio to the engine. High silicon containing aluminium alloys are used in current ... -
Two Inverse Problems In Linear Elasticity With Applications To Force-Sensing And Mechanical Characterization
(2013-06-24)Two inverse problems in elasticity are addressed with motivation from cellular biomechanics. The first application is computation of holding forces on a cell during its manipulation and the second application is estimation ...
