Energy dissipation and other studies on submerged circular twin jets
When a high velocity sutmerged water jet enters a quiescent amhient medium of the same fluid Its energy gets gradually dissipated along Its course In the surrounding medium and Its efflux velocity gets decelarated along ... -
Some aspects of cavitation phenomena in centrifugal pumps
The work reported in this thesis has a fourfold objective, namely, to study: The influence of Froude number on the inception of cavitation in radial flow pumps. The influence of prerotation on the cavitation performance ... -
Effect of pre-rotation on cavitation in centrifugal and mixed flow pumps.
It has been theoretically shown that introduction of prerotation at the impeller inlet at design point improves the cavitation performance. A qualitative assessment of this from existing data on centrifugal pump impellers ... -
Dissipation of energy of a circular jet submerged in water
This thesis deals with the study of the dissipation of energy of a high-velocity jet flowing into a standing mass of water. At the instant when the jet enters the standing pool of water, the jet possesses the maximum energy ... -
Effect of viscocity and surface tension on the taylor instability of the surface of a cavitation bubble
This thesis is devoted to a consideration of the following problem: A spherical mass of fluid of density ??, viscosity ?? and external radius R is surrounded by a fluid of density ?? and viscosity ??. The fluids are ... -
Unsteady two-Dimensional flow field behind perforated plates on a flat surface
The flow over bluff bodies with separation is one of the oldest in fluid mechanics. The separated flows would be considered to have local streamline curvature; such flows are particularly of interest in engineering due to ... -
Steady two-dimensional seepage flow analysis analytical and numerical methods
The primary aim of the present work is to study the influence of sloping boundaries with discontinuities in slopes and the effect of surfaces of seepage on seepage characteristics in case of confined and unconfined flows ... -
Entertainment co-efficient surface jet
The thesis presents the results of an experimental study on the entrainment coefficient of a circular non-buoyant surface water jet discharging into quiescent ambient water. The thesis consists of seven chapters. Chapter ... -
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 ... -
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 » ... -
In-Situ Shear Wave Velocity Measurement and Interpretation by Different Methods of Testing
A significant challenge in seismic site classification often arises from the conflicting shear wave velocity (VS) profiles often obtained using different survey methods, further complicated by uncertainties introduced when ... -
Evaluating Sustainable Transport Measures Towards Fulfilling Sustainable Development Goals
Transportation system generates significant negative externalities such as air pollution, traffic congestion, road‑traffic accidents, and substantial greenhouse‑gas emissions, that if left unaddressed, threaten to undermine ... -
Virtual Element Methods for Phase Field Fracture: Mesh Transitions, Composite Damage, and Stabilization-Free Formulations
Accurate simulation of crack propagation requires discretization methods that combine geometric flexibility with computational efficiency. Although the finite element method (FEM) and its variants remain the widely used ... -
Flood Risk Assessment in Peninsular India: Integrating Data, Multivariate Statistics, and Machine Learning
Floods are among the most significant natural hazards in India; however, their drivers, spatial coherence, and potential impacts remain poorly understood, particularly in data-scarce catchments. This thesis addresses these ... -
Mechanics of Flat-punch Indentation of Metallic Honeycombs Using High-fidelity Continuum FE Simulations
Metallic honeycombs and foams are widely used in the automotive and aerospace industries due to their desirable mechanical properties such as light-weight, high and tailorable specific stiffness, high specific strength, ... -
Analysis of Groundwater Systems Using Lumped and Distributed Hydrological Models: Applications in Indian Tropical Region
Groundwater is a critical resource for meeting agriculture, domestic, and industrial water demand, particularly in tropical regions of India. However, increasing groundwater extraction, erratic monsoonal rainfall, and ...
