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 ...
A Unified Constitutive Model For Large Elasto-plastic Deformation
(2009-07-23)
Rapid development and stiff competition in material related industries such as the automotive, demand very high precision in end products in very quick time. The transformation of raw material into an intricate-shaped final ...
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 ...
Modular Kinematic Analysis Of Planar Linkages
(2009-04-24)
This thesis has developed an efficient methodology for automatic kinematic analysis of planar linkages using the concept of modular kinematics. Unlike conventional general purpose kinematic analysis packages where each joint ...
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 ...
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 ...
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 ...
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 ...
