Short to Medium Range Forecasting Skills of the GFS Model
The reliable prediction of the South Asian monsoon rainfall and its variability is crucial for various hydrological applications and early warning systems. This study analyzes Global Fore- cast System (GFS) model generated ... -
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 ... -
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 ... -
Analysis of the Flow of Granular Materials through a Screw Conveyor
Screw conveyors are widely employed in industry for the bulk transport of particulate materials. Several studies have attempted to correlate the discharge rate with the rotation speed of the screw via experiments and ... -
Microstructure and mechanical properties of a 3D printed titanium alloy
The selective laser melting (SLM) process is increasingly being adopted for the manufacturing of metal parts as it provides better design flexibility and has the capability to produce near net shape complex parts, which ... -
Probabilistic Analysis of Radionuclide Transport for Radioactive Waste Disposal Systems in Soil and Fractured Rocks
The safe management of radioactive waste disposal facilities is increasingly becoming a necessary condition for the future development of nuclear industry. To ensure long-term safety of these disposal facilities, performance ... -
Macroscopic modelling of heterogeneous, disordered road traffic flow
The groundwork for much of the existing traffic flow theory was laid in the 1950s and 1960s by researchers from developed economies like the United States. The car-following modelling approach, which is arguably the most ... -
Shaking Table Studies on Seismic Response of Unreinforced and Geosynthetic Reinforced Soil Slopes
Experiences from recent earthquake records all over the world suggest that reinforced soil slopes provide better resistance to the seismic forces and possess higher yield accelerations compared to unreinforced slopes. ... -
Processing mediated polymorphism in PVDF-based dielectric polymers and their application
The ever-increasing demand in electronic devices, piezoelectric materials such as ceramics, polymers and polymer ceramic composites with enhanced piezoelectric and dielectric properties has become the focus of many ... -
Insights of Evaporation Dynamics of an Interacting Linear Array of Droplet System
Manipulation of an array of sessile droplets organized in an ordered structure turns out to be of immense consequence in a wide variety of applications ranging from photonics, near field imaging and inkjet printing on one ... -
Novel Numerical Procedures for Limit Analysis: Implementation to Planar, Axisymmetric and Three-Dimensional Geomechanics Stability Problems
The Current research in the field of computational limit analysis dwells upon the development of numerical tools which are sufficiently efficient and robust to be used in engineering practices. This places demands on the ... -
Geochemical and isotopic study of the Lonar and Dhala impact craters and jarosites from Kutch, India as analogues to understand planetary surface processes
Impact cratering and aqueous alteration are two important processes that have modified the Earth’s surface over time and better understanding of these processes on Earth allow us to understand the surface evolution of other ... -
Stable isotope geochemistry of carbonatites: New insights into the petrogenesis and evolution
Carbonatites are carbonate-rich magmatic rocks that are commonly thought of having a mantle origin and are thus, of great interest to geologist for understanding the chemical evolution of the upper mantle. This thesis ... -
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 ... -
The Role of Self-Recirculating Casing Treatment on Axial Compressor and Its Aeroelastic Behavior
The modern-day axial compressor stages in a gas turbine engine play a vital role in generating the high-pressure ratios by operating at the limits of their design. Aerodynamic instabilities such as rotating stall and surge ... -
Effect of Sintering on Microstructure and Mechanical Properties of Air Plasma Sprayed 7 wt.% Y2O3 Stabilized ZrO2
Air plasma sprayed (APS) 7 wt.% Y2O3 stabilized ZrO2 (7YSZ) coating is conventionally used for thermal insulations (in form of thermal barrier coating, TBC) in various hotter sections of land-based gas turbine engines and ... -
Sound Radiation from Rectangular Panels with Rectangular Cut-out/s
This is largely an analytical investigation and the objective of this study is to compute sound power radiated from rectangular panels that are placed in an infinite baffle (or a rigid wall) and that have rectangular ... -
Bioremediation of Mechanically and Biologically Treated Waste Of Bangalore City: An Experimental and Numerical Study
Remediation of the existing MSW dumpsites has received considerable attention these days and there is an urgent need to address this issue in order to maintain the over hygiene of the urban environment. An approach consisting ... -
Seasonal Isotopic Variability and Major Ion Chemistry of the Cauvery River Basin, Peninsular India
Surface water and groundwater interactions are inherently complex because they occur across a range of spatial and temporal scales. This thesis envisages to improve our understanding of surface water and groundwater in ... -
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 ...
