Instabilities In Supersonic Couette Flow
(2010-07-15)Compressible plane Couette flow is studied with superposed small perturbations. The steady mean flow is characterized by a non-uniform shear-rate and a varying temperature across the wall-normal direction for an appropriate ... -
Acoustic Source Characterization Of The Exhaust And Intake Systems Of I.C. Engines
(2010-07-15)For an engine running at a constant speed, both exhaust and intake processes are periodic in nature. This inspires the muffler designer to go for the much easier and faster frequency domain modeling. But analogous to ... -
Remedial Measures For Alkali Induced Heave In Soils
(2010-07-15)Sub-surface soil pollution by various processes with high concentration of contaminants can significantly alter geotechnical properties of soils causing unexpected failures of structures founded on them. The changes can ... -
Design Of Two-Axis Displacement-Amplifying Compliant Mechanisms Using Topology Optimization
(2010-07-14)This thesis deals with the design of two-axis displacement-amplifying compliant mechanisms (DaCMs) using topology optimization. The two-axis compliant mechanisms considered here are XY positioners and two-axis inertial ... -
Studies Of Glass Formation In Al-La-Ni And Mg-TM-RE Alloys With A Structure Mapping Approach
(2010-07-14)The glass-forming composition ranges in Al-La-Ni and Mg-TM (Cu, Zn)-Y alloys were predicted using Miedema’s model. Glass-forming abilities of Al-La-Ni alloys and Mg-Cu-RE alloys were studied in terms of reduced glass ... -
Engineering Analysis Of Pichia Pastoris Fermentation
(2010-07-14)In recent years, several industrial yeasts, owing to their robust growth and certain other characteristics, have been developed as recombinant host systems for commercial production of heterologous proteins. One such ... -
Theoretical And Experimental Studies Of Capillary Pumped Loop And Loop Heat Pipe
(2010-07-13)Capillary pumped loop (CPL) and loop heat pipe (LHP), are two-phase heat transport devices which rely on surface tension induced by a fine pore wick to drive a working fluid in a loop. These are based on a working principle ... -
Mechanism And Control Of Sulphuric Acid Induced Heave in Soils
(2010-07-12)The escalating pollution of the environment has been one of the greatest concerns of science in recent years. Industrial advances in agriculture, expansion of chemical industries and a general change in lifestyle all over ... -
Turbulent Jet Diffusion Flame : Studies On Lliftoff, Stabilization And Autoignition
(2010-07-09)This thesis is concerned with investigations on two related issues of turbulent jet diffusion flame, namely (a) stabilization at liftoff and (b) autoignition in a turbulent jet diffusion flame. The approach of Conditional ... -
Flow Over A Circular Cylinder With A Flexible Splitter Plate
(2010-07-08)Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ... -
Numerical Studies On Ductile Fracture Of Pressure Sensitive Plastic Solids
(2010-07-08)Experimental studies have shown that the yield strength of many important engineering materials such as polymers, ceramics and metallic glasses is dependent on hydrostatic stress. In addition, these materials may also ... -
Developement Of Aluminium Foam : An Experimental And Numerical Study
(2010-07-06)Metal foams are lightweight structures and have large use in many components acting as impact energy absorbers. They have exceptional mechanical, thermal and acoustic properties. The design or selection of foam for packaging ... -
A Study Of A Vortex Particle Method For Vortex Breakdown Phenomena
(2010-07-06)Vortex breakdown is an important phenomenon observed in swirling flows involving the development of a stagnation point on the axis of the vortex followed by a region of recirculation when the swirl increases beyond a ... -
Effect Of Free-Volume On The Fracture And Fatigue Of Amorphous Alloys
(2010-07-01)Bulk metallic glasses (BMGs) are a new class of structural materials and exhibit unique combinations of mechanical properties. As a result, their mechanical behavior has been an active area of scientific pursuit in the ... -
Micro-PIV Study Of Apparent Slip Of Water On Hydrophobic Surfaces
(2010-07-01)The condition of no relative velocity of fluid past solid is termed as ‘no-slip boundary condition’. This condition is a general observation in fluid mechanics. However, several research groups have recently reported slip ... -
Impact Of Large-Scale Coupled Atmospheric-Oceanic Circulation On Hydrologic Variability And Uncertainty Through Hydroclimatic Teleconnection
(2010-06-14)In the recent scenario of climate change, the natural variability and uncertainty associated with the hydrologic variables is of great concern to the community. This thesis opens up a new area of multi-disciplinary research. ... -
