Non-Dimensional Kinetoelastic Maps for Nonlinear Behavior of Compliant Suspensions
(2018-02-18)
Compliant suspensions are often used in micromechanical devices and precision mechanisms as substitutes for kinematic joints. While their small-displacement behavior is easily captured in simple formulae, large-displacement ...
Semisolid Die Casting of Wrought A6061 Aluminium Alloy
(2018-04-02)
The mechanical properties achieved with high performance wrought aluminium alloys are
superior to cast aluminum alloys. To obtain an intricate shaped component, wrought alloys are commonly subjected to forging followed by ...
Adaptive Mesh Redistribution for Hyperbolic Conservation Laws
(2018-03-19)
An adaptive mesh redistribution method for efficient and accurate simulation of multi dimensional hyperbolic conservation laws is developed. The algorithm consists of two coupled steps; evolution of the governing PDE ...
Numerical Simulation of Convection Dominated Flows using High Resolution Spectral Method
(2018-03-19)
A high resolution spectrally accurate three-dimensional flow solver is developed in order to simulate convection dominated fluid flows. The governing incompressible Navier Stokes equations along with the energy equation ...
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 ...
Studies On Transport Phenomena During Solidification In Presence Of Electromagnetic Stirring
(2010-07-20)
In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing the fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ...
A Comparative Study Of The Numerical Techniques Used In The Wrinkling Analysis Of Membranes
(2010-07-19)
This work is a comparative study of the various numerical techniques used for analyzing membranes. Membrane analysis is complicated by the fact that local instabilities occur in membranes in the form of small waves or ...
Motion Space Analysis of Smooth Objects in Point Contacts
(2018-07-19)
The present work studies instantaneous motion of smooth planar and spatial objects in unilateral point contacts. The traditional first-order instantaneous kinematic analysis is found insufficient to explain many common ...
Dynamics of Bubbles and Drops in the Presence of an Electric Field
(2018-07-16)
The present thesis deals with two-phase electrohydrodynamic simulations of bubble and droplet dynamics under externally applied electric fields. We used the Coupled Level-Set and Volume-of-fluid method (CLSVOF) and two ...
Droplet Growth in Moist Turbulent Natural Convection in a Tube
(2018-07-04)
Droplet growth processes in a cumulus cloud, beginning from its inception at sub-micron scale up to drizzle drop size of few hundred microns, in an average duration of about half hour, has been a topic of intense research. ...
