Spray morphology and droplet characteristics in gas centered swirl coaxial (GCSC) atomizers
Studies on liquid atomization and spray formation in coaxial type atomizers are necessary to improve the performance of liquid propellant rocket engines. Recess ratio, expressed as the ratio of orifice recess length to ... -
Stabilisation Of Black Cotton Soil By Lime Piles
(Indian Institute of Science, 2006-07-07)Modification of black cotton soils by chemical admixtures is a common method for stabilizing the swell-shrink tendency of expansive soils. Advantages of chemical stabilization are that they reduce the swell-shrink tendency ... -
Stabilised Rammed Earth For Walls : Materials, Compressive Strength And Elastic Properties
(2011-01-10)Rammed earth is a technique of forming in-situ structural wall elements using rigid formwork. Advantages of rammed earth walls include flexibility in plan form, scope for adjusting strength and wall thickness, variety of ... -
Stability Numbers For Slopes With Associated And Non-Associated Flow Rule And Shake Table Liquefaction Studies
(2007-10-23)Based upon the upper bound limit analysis, the stability numbers have been developed for a two-layered soil slope both for an associated flow rule material and for a homogeneous slope with non-associated flow rule material. ... -
Stability Of Double-Diffusive Finger Convection In A Non-Linear Time Varying Background State
(2010-09-06)Convection set up in a fluid due to the presence of two components of differing diffusivities is known as double diffusive convection. Double diffusive convection is observed in nature, in oceans, in the formation of certain ... -
Stability of wall-bounded compressible shear flows
In this work, the linear stability of compressible shear flows in channels and pipes are studied. A steady fully-developed laminar flow of an ideal gas, driven in a channel and a pipe by a constant body acceleration, is ... -
Stable isotope and biogeochemical study of arsenic contamination in shallow groundwater at seasonal time intervals from West Bengal (Nadia district)
Seasonal monitoring of groundwater is essential to ascertain safe water for the population and ecosystem for drinking, irrigation, domestic purposes and to keep track of groundwater quality with natural (climate change ... -
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 ... -
Stable Isotopic Composition of Rice Grain Organic Matter as an Archive of Monsoonal Climate
(2018-08-30)Rice grows in saturated soil water condition and its requirement for water is highest amongst other cereal crops. In India, the southwest monsoon wind regime brings rainfall that provides a favourable environment for rice ... -
A stable Strontium isotopic (δ88/86Sr) study of seawater from the Bay of Bengal, coastal groundwater from the Bengal Basin, and the Ganges, Brahmaputra, Mahanadi, and Godavari rivers in India
Strontium (Sr) is an alkaline earth element that has four naturally occurring stable isotopes, 84Sr, 86Sr, 87Sr and 88Sr. During measurements of the radiogenic Sr isotope ratio (87Sr/86Sr), which is a widely used tracer ... -
Stall Flutter of a Cascade of Blades at Low Reynolds Number
(2017-12-05)Due to the requirements for high blade loading, modern turbo‐machine blades operate very close to the stall regime. This can lead to flow separation with periodic shedding of vortices, which could lead to self induced ... -
Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude. The most widely ... -
State and Parameter Estimation in Water Distribution Systems
Water Distribution Systems (WDS) are one of the most important infrastructures in a society, which has a direct impact on human lives. Water authorities around the world are expected to supply the required amount of water ... -
Static and Dynamic Behavior of Reinforced Masonry : Experimental and Analytical Investigations
(2018-07-18)The most common form of dwellings in rural and semi-urban areas of India and other developing countries around the globe are one/two storey unreinforced masonry (URM) buildings. It is well known that such masonry buildings ... -
Static And Dynamic Behaviour Of Cement Stabilised Rammed Earth Panels And Building Models
(2011-01-10)Rammed earth is one of the earliest building materials used for structural walls. Stabilised rammed earth is a variant of traditional or pure rammed earth that involves addition of a small amount of cement to improve ... -
Static Balancing of Rigid-Body Linkages and Compliant Mechanisms
(2018-03-07)Static balance is the reduction or elimination of the actuating effort in quasi-static motion of a mechanical system by adding non-dissipative force interactions to the system. In recent years, there is increasing recognition ... -
Statics of Shallow Bistable Arches
Bistable arches have two force-free stable equilibrium configurations. They also show multimodality by switching between their stable states in multiple deformation pathways. These two attributes and their nonlinear ... -
Steady Sedimentation of Particles in Long Vertical Tube and Effect of End Boundary Conditions on Convective Motion
Sedimentation – settling of particles in a fluid- is observed in nature like rain droplets and dust particles in the atmosphere, and in a variety of industrial processes, like to clarify liquid as well as separate particles ... -
Steady State Dynamics Of Systems With Fractional Order Derivative Damping Models
(2011-01-10)Rubber like materials find wide applications in damping treatment of structures, vibration isolations and they appear prominently in the form of hoses in many structures such as aircraft engines. The study reported in this ...
