    • 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 ...
