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 ...
Topology Optimization Of Composite Heat-Sinks Involving Phase-Change Material
(2010-08-16)
The principal goal of this thesis is to develop a systematic method for the design of composite heat sinks (CHSs) that serve as passive and transient cooling devices for microelectronics. This is accomplished by posing the ...
Numerical Simulations Of Void Growth In Ductile Single Crystals
(2010-09-03)
The failure mechanism in ductile materials involves void nucleation, their growth and subsequent coalescence to form the fracture surface. The voids are generated due to fracture or debonding of second phase particles or ...
Sedimentation Of Heavy Particles In Turbulence
(2010-08-06)
Behavior of particles in buoyancy driven turbulent flow at Ra ≈ 10º is investigated experimentally. The volume fraction of the particles is low enough for the inter particle influence to be neglected, the mass loading ...
Role Of Solid Phase Movement And Remelting On Macrosegregation And Microstructure Formation In Solidificaiton Processing
(2010-08-25)
Melt convection and solid phase movement play an important role in solidification processes, which significantly influence the formation of grain structures and solute segregations. In general, the melt convection and grain ...
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 ...
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 ...
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 ...
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 ...
A Prestress Based Approach To Rotor whirl
(2010-06-02)
Rotordynamics is an important area in mechanical engineering. Many machines contain rotating parts. It is well known that rotating components can develop large amplitude lateral vibrations near certain speeds called critical ...
