Kinematic And Static Analysis Of Over-Constrained Mechanisms And Deployable Pantograph Masts
(2011-01-19)
Foldable and deployable space structures refer to a broad category of pre-fabricated structures that can be transformed from a compact folded configuration to a predetermined expanded configuration. Such deployable structures ...
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 ...
Unsteady Two Dimensional Jet with Flexible Flaps at the Exit
(2017-11-13)
The present thesis involves the study of introducing passive exit flexibility in a two dimensional starting jet. This is relevant to various biological flows like propulsion of aquatic creatures (jellyfish, squid etc.) and ...
Experimental and Numerical Investigation of an Evaporating Meniscus in a Capillary Slot : Microscale and Pore Scale Studies
(2018-08-09)
An evaporating meniscus formed by a wetting °uid in a heated capillary slot with capillary driven °flow is numerically and experimentally investigated at the microscale and pore scale.
In the microscale analysis, the ...
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 ...
Buoyancy Driven Turbulence In A Vertical Pipe
