Premixed Turbulent Combustion Of Producer Gas In Closed Vessel And Engine Cylinder
(2010-10-22)Producer gas derived from biomass is one of the most environment friendly substitutes to the fossil fuels. Usage of producer gas for power generation has effect of zero net addition of CO2 in atmosphere. The engines working ... -
A Magnesia Based Sustainable Method For De-Fluoridation Of Contaminated Groundwater
(2010-10-14)Groundwater is a major and sometimes lone source of drinking water worldwide. The chemical composition of groundwater is a combined product of the composition of water that enters the aquifer and its reaction with various ... -
Optimum Design Of Retaining Structures Under Static And Seismic Loading : A Reliability Based Approach
(2010-10-14)Design of retaining structures depends upon the load which is transferred from backfill soil as well as external loads and also the resisting capacity of the structure. The traditional safety factor approach of the design ... -
Seismic Response Of Geosynthetic Reinforced Soil Wall Models Using Shaking Table Tests
(2010-10-14)Use of soil retaining walls for roads, embankments and bridges is increasing with time and reinforced soil retaining walls are found to be very efficient even under critical conditions compared to unreinforced walls. They ... -
Concrete Fracture And Size Effect - Experimental And Numerical Studies
(2010-10-14)Most materials including concrete have pre-existing flaws or defects. The fracture energy of concrete is a basic material property needed to understand fracture initiation and propagation in concrete. Whether fracture ... -
Reactive Hot Pressing Of ZrB2-Based Ultra High Temperature Ceramic Composites
(2010-10-08)Zirconium- and titanium- based compounds (borides, carbides and nitrides) are of importance because of their attractive properties including: high melting temperature, high-temperature strength, high hardness, high elastic ... -
Accurate Computational Algorithms For Hyperbolic Conservation Laws
(2010-10-08)The numerics of hyperbolic conservation laws, e.g., the Euler equations of gas dynamics, shallow water equations and MHD equations, is non-trivial due to the convective terms being highly non-linear and equations being ... -
Defluoridation Of Drinking Water Using A Combined Alum-Activated Alumina Process And Nanoscale Adsorbents
(2010-10-08)Excess Fluoride in drinking water is a cause for concern in several countries in the world. Various techniques have been developed to mitigate the harmful effects of fluoride. In the present work, a combined alum and ... -
An Assessment Of The Simulation Of Monsoon And Inter Tropical Convergence Zone In Coupled Ocean-Atmosphere Models
(2010-10-08)Monsoons and Intertropical Convergence Zones (ITCZ) exhibit variability at various temporal and spatial scales. The temporal scale of variability encompasses scales from the intraseasonal through interannual to interdecadal ... -
Study Of Evaluation Of Texture And Microstructure During Different Modes Of Rolling And Annealing Of Two Phase α-β Brass
(2010-09-28)It is well known that texture and microstructure play a crucial role in determining properties of metallic materials. The evolution of microstructure and texture during deformation and annealing of copper and some copper ... -
Impact Assessment Of Climate Change On Hydrometeorology Of River Basin For IPCC SRES Scenarios
(2010-09-28)There is ample growth in scientific evidence about climate change. Since, hydrometeorological processes are sensitive to climate variability and changes, ascertaining the linkages and feedbacks between the climate and the ... -
New Solution Methods For Fractional Order Systems
(2010-09-24)This thesis deals with developing Galerkin based solution strategies for several important classes of differential equations involving derivatives and integrals of various fractional orders. Fractional order calculus finds ... -
Hydrodynamics Of An Oscillating Foil With A Long Flexible Trailing Edge
(2010-09-24)In nature, many swimming and flying creatures use the principle of oscillatory lift-based propulsion. Often the flapping element is flexible, totally or partially. The flow dynamics because of a flexible flap is thus of ... -
Studies In Stability Of Newtonian And Viscoelastic Fluid Flow Past Rigid And Flexible Surfaces
(2010-09-23)The surface oscillations in a deformable wall are known to induce an instability in the adjacent flow even in the absence of inertia. This instability, if understood properly, can be exploited to generate a well-mixed flow ... -
The Effect Of Energy Deposition In Hypersonic Blunt Body Flow Field
(2010-09-23)A body exposed to hypersonic flow is subjected to extremely high wall heating rates, owing to the conversion of the kinetic energy of the oncoming flow into heat through the formation of shock waves and viscous dissipation ... -
Effects Of Reinforcement Parameters On The Behavior Of Geosynthetic Reinforced Foundation Beds
(2010-09-22)Use of geosynthetics for reinforcing soil beds supporting shallow foundations has gained tremendous popularity in recent times. In this thesis, to study and understand the behaviour of geosynthetics reinforced soil ... -
