Modeling the Dependence Structure of Hydroclimatic Extremes
Analysis of extremes in a complex interacting hydroclimatic system is challenging due to rarity of events, small sample size, poor state of data or missing data, lack of statistical tools for analyzing observed changes and ...
Studies on a New Spinning Disc-Spinning Bowl Contactor/Mixer
Increased focus on continuous synthesis of fine chemicals and pharmaceuticals has led to resurgence of process intensification. In this thesis we introduce a new continuous contactor. It works on the principle of impinging ...
Development of a low modulus Ti-Nb-Ta-O alloy for orthopedic applications
Ti-Nb-Ta-Zr based β-Titanium alloys are currently projected as potential candidates for use in orthopaedic implants owing to their low elastic modulus and use of non-toxic elements. However, most of these alloys contain ...
Analysis and Design of Organic Rankine Cycle based Power Plants
Solving the world’s energy crisis, and mitigating anthropogenic climate change, requires efficiently harnessing non-polluting renewable energy. Organic Rankine cycle (ORC) can be useful in this regard. ORC is Rankine cycle ...
Heat Transfer and Visualization Studies in the Evaporator of a Flat Loop Heat pipe
Heat pipes are extensively used in spacecraft thermal control and electronics cooling for transfer of heat from high heat flux zones to low heat flux zones. The major advantage of heat pipe is it can transfer high heat ...
Design of Planar Supersonic Wind Tunnel Nozzle
This thesis revisits the design of a planar supersonic nozzle for a supersonic wind tunnel using
the method of characteristics (MOC) and Computational Fluid Dynamics (CFD). While design
of a converging-diverging (CD) ...
Parameter Estimation to Determine the Groundwater Flow and Seawater Intrusion in a Coastal Aquifer of Karnataka, India
Seawater Intrusion (SWI) into the fresh groundwater aquifers is one of the major hydrological problems in coastal regions. This global issue is aggravated by increasing demands for fresh groundwater due to on-going ...
Improvement of High Temperature Oxidation Behavior of ‘w’ Free Y strengthened Co-based Superalloys through Alloying Addition
The discovery of coherent g-g’ microstructure in Co-Al-W and Co-Al-Mo-Nb/Ta systems represents new possibilities for turbine engines materials. Their chemical and mechanical properties are similar to commercially successful ...
Lattice Boltzmann Relaxation Schemes for High Speed Flows
The lattice Boltzmann method (LBM) has emerged as a highly efficient model
for the simulation of incompressible
flows in the last few decades. Its extension to
compressible
flows is hindered by the fact that the ...
Interaction behavior and droplet characteristics of multi-injector sprays
The injector faceplate of a liquid propellant rocket engine is comprised of numerous single-element atomizers to inject propellants into the engine thrust chamber. The sprays from these single-element atomizers interact ...
