    • An Experimental Study Of Instabilities In Unsteady Separation Bubbles 

      Das, Shyama Prasad (Indian Institute of Science, 2007-06-11)
      The present thesis is an experimental study of some aspects of unsteady two dimensional boundary layers subject to adverse pressure gradient. An adverse pressure gradient usually leads to boundary layer separation or an ...

    • Studies On Momentum, Heat And Mass Transfer In Binary Alloy Solidification Processes 

      Chakraborty, Suman (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 ...

    • Development Of A Single Cylinder SI Engine For 100% Biogas Operation 

      Kapadia, Bhavin Kanaiyalal (Indian Institute of Science, 2007-05-21)
      This work concerns a systematic study of IC engine operation with 100% biogas as fuel (as opposed to the dual-fuel mode) with particular emphasis on operational issues and the quest for high efficiency strategies. As a ...

    • A Finite Element Investigation Of Brittle Fracture During Spherical Nanoindentation Of Thin Hard Films 

      Sriram, K (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 ...

    • Turbulent Mixed Convection 

      Ramesh Chandra, D S (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 ...

    • Transport Phenomena In Laser Surface Alloying: A Numerical Investigation 

      Mohan Raj, P (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 ...

    • Computational Modelling Of Heat Transfer In Reheat Furnaces 

      Harish, J (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 ...

    • The Effect Of Viscosity On The Erosion Of Gradient- Zone In A Laboratory Solar Pond 

      Pradhan, Sudeep S (Indian Institute of Science, 2006-08-24)
      Double diffusive phenomena occur in many natural systems and in a variety of engineering applications, such as solar ponds. In a solar pond, the erosion of gradient zone due to convection and diffusion is the main cause ...

    • Investigations On High Rayleigh Number Turbulent Free Convection 

      Puthenveettil, Baburaj A (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 ...
