Laminar Conjugate Natural Convection And Surface Radiation In Horizontal Annuli
(2010-07-29)
Numerical studies of two-dimensional laminar conjugate natural convection flow and heat transfer in horizontal annuli formed between inner heat generating solid cylinders and outer isothermal circular boundary are performed ...
Transfer Layer Formation And Friction In Extrusion Of Aluminum : An Experimental Study Using A High Temperature Vacuum Based Pin-On-Disc Machine
(2010-09-21)
Hot extrusion of aluminum is widely practiced in industries for economic production of structural components. The surface finish and tolerance of the extruded components, both from design and aesthetic requirement, are ...
A Study Of Four Problems In Nonlinear Vibrations via The Method Of Multiple Scales
(2010-12-03)
This thesis involves the study of four problems in the area of nonlinear vibrations, using the asymptotic method of multiple scales(MMS). Accordingly, it consists of four sequentially arranged parts.
In the first part ...
Stability Of Double-Diffusive Finger Convection In A Non-Linear Time Varying Background State
(2010-09-06)
Convection set up in a fluid due to the presence of two components of differing diffusivities is known as double diffusive convection. Double diffusive convection is observed in nature, in oceans, in the formation of certain ...
Experiments On Natural Ventilation In A Room And Real Source-Sink Pairs
(2010-09-06)
The present work consists of two parts: experimental study of natural ventilation in a model room and the flow associated with a source-sink pair.
The first part describes the natural ventilation of a model room of size ...
Experimental And Theoretical Studies In Fatigue Damage Modeling
(2010-12-07)
This thesis has two parts.
In the first part, we use the results of new fatigue experiments conducted with variable load levels as well as variable stress ratios to critically assess three (two old and one relatively ...
Breakout Noise From The Coupled Acoustic-Structural HVAC Systems
(2010-07-19)
Noise control in the heating, ventilation and air-conditioning (HVAC) systems is one of the critical design parameters in measuring the occupant comfort. The noise generated by air-handling units propagates through the ...
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 ...
Asymptotic Analysis Of The Dispersion Characteristics Of Structural Acoustic Waveguides
(2010-04-12)
In this work, we study the coupled dispersion characteristics of three distinct structural-acoustic waveguides, namely: -(1) a two-dimensional waveguide, (2) a fluid-filled circular cylindrical shell and (3)a fluid-filledelliptic ...
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 ...
