Modulation of Metal Fluxes and their Isotope Ratios in the Ganga (Hooghly) Estuary
This thesis aims at constraining the impact of estuarine processes on the net riverine fluxes of select metals and their isotopic composition to seawater. I studied the Ganga (Hooghly) River estuary, a monsoon-dominated ... -
Robust and Accurate Kinetic Schemes based on Flexible Velocities for Compressible Flows
Kinetic theory based schemes offer a unique approach to numerically solving the hyperbolic nonlinear Euler equations. These methods start with the Boltzmann equation as the governing equation at the kinetic level and then ... -
Machine Learning Methods for Soil property prediction using VNIR and MIR Spectroscopy
Soil plays a key role in food security, freshwater regulation, biodiversity and climate mitigation. Soil intersects directly or indirectly with at least seven of the United Nations Sustainable Development Goals. Among the ... -
Structure and Polar Properties of SrTiO3-xNa0.5Bi0.5TiO3 Ferroelectric System
Ferroelectric materials exhibit interesting dielectric and piezoelectric properties. While for over six decades, lead-zirconate titanate (PZT) has been the most sought after piezoelectric material for actuator, transducer, ... -
Improving Mechanical Properties and Self-Healing by Dynamic Bonds at Interface in Carbon Fiber Reinforced Epoxy Laminate and its Recycling
Carbon fiber-reinforced epoxy (CFRE) laminates have revolutionized aerospace engineering due to their exceptional strength-to-weight ratio, corrosion resistance, and design flexibility. However, challenges such as weak ... -
Some studies on resistance to flow in rigid bed open channels
This thesis embodies the results of the investigations carried out by the author on the problem of resistanc-e to flow through open channels. Based on these> the author was able to modify Manning's formula, so as to ... -
Prediction of cavitation damage
A theory which gives a unified picture of (1) the bubble collapse, (ii) the transmission of the collapse pressure, and (iii) the deformation of the material due to the work done by the bubble is proposed, incorporating ... -
Studies on air entrainedflow
The important factors affecting air entrainment by flowing water are found to be slope and roughness. Results showing the effect of slope, length of the chute, side wall, and different conditions of roughness are presented ... -
Studies on submerged jets
This thesis deals with the studies on submerged jets. In the first part of the thesis, a critical survey of the existing literature has been made with a bibliographical chart on the subject up to date. The second part ... -
Studies on the resistance to the flow of water in curved pipes and pipe bends
This thesis contains the theoretical and experimental investigations carried out by the author on the resistance offered to the flow of water curved curved pipes and pipe bends The thesis is in three parts In Part I » ... -
Kinematics and Rheology of Complex Fluids: Active Suspensions and Dry Granular Materials
This work focuses on two problems in complex fluids, namely collective dynamics of suspensions of self-propelled particles and the rheology of dry granular materials. In both systems, interaction between the particles is ... -
Studies in the computation of thermodynamics
Thermodynamic properties of substances like entropy and enthalpy are important in the study and design of the processes involving liquefaction, solidification, refrigeration, heat transfer, gas separation, and in chemical ... -
Studies on hydrodynamics and liquid-solid contacting in trickle-bed reactors
In trickle-bed reactors, gas and liquid flow concurrently downwards over fixed beds of catalysts. The reactors find wide application for three-phase contacting in chemical, petrochemical, petroleum and fermentation industries, ... -
Studies in the computation of thermodynamic properties; v.2
Thermodynamic properties of substances like entropy and enthalpy are important in the study and design of the processes involving liquefaction, solidification, refrigeration, heat transfer, gas separation, and in chemical ... -
Studies in heat transfer during condensation of vapours
Till until now surface tension is not taken into consideration. So, the preset work is take up to (1) Collect data on film wise condensation of vapours of organic liquids and aspotropic mixtures. (2) To check the existing ... -
Studies in condensation of vapours
for the same identical conditions, dropwise condensation gives higher heat transfer coefficients compared to filmwise type of condensation. This shows that if dropwise condensation is assured, the condensation surface can ... -
Studies on laminar boundary layer diffusion flames in a confined flow.
When a gaseous fuel is uniformly injected through a porous flat plate into a laminar boundary layer of an oxidant stream, a two-dimensional diffusion flame can be established which exhibits some special features. Despite ... -
Low Reynolds Number Vortex Shedding In Three-dimensional Flows
Understanding of the flow behind the bluff body poses a great challenge and remains almost entirely in the empirical and descriptive realm of knowledge. Flow in the wake of bluff bodies is characterized by the phenomenon ... -
Dynamic behavior of electro-rheological fluid sandwich beams
Electrorheological (ER) fluids are fluids with controllable rheological properties. The study of change in rheology of suspensions due to application of electric field is of interest both from academic and industrial points ... -
Development and critical assessment of a new flic method for base flows
The motivation for the present work stems from two complex base flow problems of relevance to satellite launch vehicles, namely the flow about the base of a rocket body containing an exhaust jet and the aerodynamics of ...
