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 ...
Transport Phenomena In Laser Surface Alloying: A Numerical Investigation
(Indian Institute of Science, 2006-08-24)
A comprehensive, transient three-dimensional model of a single-pass laser surface alloying process has been developed and used to examine the heat, momentum and species transport phenomena. A numerical study is performed ...
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 Comparative Study Of Different Numerical Techniques Used For Solving Incompressible Fluid Flow Problems
(2010-06-03)
Past studies (primarily on steady state problems) that have compared the penalty and the velocity-pressure finite element formulations on a variety of problems have concluded that both methods yield solutions of comparable ...
Finite Element And Experimental Studies On Fracture Behavior Of Bulk Metallic Glasses
(2011-01-19)
The objective of this thesis is to study the fracture behavior of bulk metallic glasses. For this purpose, detailed finite element investigation of the mode I and mixed mode (I and II) stationary crack tip fields under ...
Cylindrical Fretting And Delamination : Axisymmetric Static And Dynamic Analysis
(2011-01-17)
Axisymmetric analysis of cylindrical contacts is considered in the context of axisymmetric assemblies such as shrink-fits. Fretting fatigue induces sub-critical cracks along the contact interface of press fits especially ...
Experimental Investigation Of Rheocasting Using Linear Electromagnetic Stirring
(2011-02-09)
In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ...
