Cooling Of Electronics With Phase Change Materials Under Constant Power And Cyclic Heat Loads
(2009-12-14)
The trend in the electronic and electrical equipment industry towards denser and more powerful product requires a higher level of performance from cooling devices. In this context, passive cooling techniques such as latent ...
Experimental And Finite Element Study Of Elastic-Plastic Indentation Of Rough Surfaces
(2009-06-24)
Most of the surfaces have roughness down to atomic scales. When two surfaces come into contact, the nature of the roughness determines the properties like friction and wear. Analysis of the rough surface contacts is always ...
Computational Modelling Of Heat Transfer In Reheat Furnaces
(Indian Institute of Science, 2006-08-24)
Furnaces that heat metal parts (blooms) prior to hot-working processes such as rolling or forging are called pre-forming reheat furnaces. In these furnaces, the fundamental idea is to heat the blooms to a prescribed ...
Design And Manufacturing Of Impact Resisting Structures (Aluminium Foam)
(2009-09-02)
Metal foams have found increasing applications in a wide range of structural and functional products, due to their exceptional mechanical, thermal, acoustic and electrical properties and offer great potential for lightweight ...
A New Insight Into Recursive Forward Dynamics Algorithm And Simulation Studies Of Closed Loop Systems
(2009-04-02)
Rigid multibody systems have been studied extensivley due to its direct application in design and analysis of various mechanical systems such as robots and spacecraft structures. The dynamics of multibody system is governed ...
A Finite Element Investigation Of Brittle Fracture During Spherical Nanoindentation Of Thin Hard Films
(Indian Institute of Science, 2006-12-14)
Hard ceramic films of micrometric thickness deposited on a soft metallic substrate have ushered in a new era in the fabrication of structural, tribological, microelectronic and optical components. The mechanical performance ...
Studies On Momentum, Heat And Mass Transfer In Binary Alloy Solidification Processes
(Indian Institute of Science, 2007-06-06)
The primary focus of the present work is the development of macro-models for numerical simulation of binary alloy solidification processes, consistent with microscopic phase-change considerations, with a particular emphasis ...
Tribology Of Aluminium Alloys Against Steel Under Boundary Lubricated Condition
(2009-04-15)
Aluminium silicon alloy has been found to be advantageous in many automobile components like pistons, cylinders, brakes and clutches. The main objective in using these alloys is to obtain lightweight and low friction ...
Turbulent Mixed Convection
(Indian Institute of Science, 2006-08-28)
Turbulent mixed convection is a complicated flow where the buoyancy and shear forces compete with each other in affecting the flow dynamics. This thesis deals with the near wall dynamics in a turbulent mixed convection ...
Investigations On High Rayleigh Number Turbulent Free Convection
(Indian Institute of Science, 2005-08-31)
High Rayleigh number(Ra) turbulent free convection has many unresolved
issues related to the phenomenology behind the flux scaling, the
presence of a mean wind and its effects, exponential probability
distribution ...
