Microscale mechanical behaviour of ceramic matrix composites considering processing e ects
The current work explores the phenomenon of microscale damage mechanism driven quasi- ductile behaviour of C/BN/SiC ceramic matrix composite (CMC) at the microscale focusing on process-microstructure-property correlations. ... -
Experimental study of the flow of granular media through a horizontal screw feeder system
A significant fraction of the materials handled in the chemical, food-processing, and pharmaceutical industries are particulate in nature. Screw feeder systems are often employed in such scenarios to achieve their bulk ... -
Assessment and Monitoring Of Hydrometeorological Variables And Extreme Conditions for Present and Future Climate Change Scenarios
Monitoring and assessment of Hydrological/hydrometeorological Variables (HVs) like streamflow, soil moisture, precipitation, and temperature are essential for various applications such as prediction/forecasting of natural ... -
Multi-vehicle anticipation-based models for describing driver behaviour in heterogeneous and disorderly traffic conditions
Driver behaviour models are widely used in the traffic engineering literature and practice. They are used for understanding drivers’ manoeuvring decisions in traffic streams. They also form the building blocks of microscopic ... -
Design and development of lateral force-controlled tribosystems
In a tribo-system, the frictional resistance during a sliding process depends on several parameters. These parameters include the interacting materials, their surface topography, contact conditions such as normal load, ... -
Cerium Oxide-based Degradable Polymer Nanocomposites for Bone Tissue Engineering
The incidences of bone-related disorders is growing steeply worldwide because of acute trauma, diseases related to aging, and obesity. Bone has a natural regenerative capacity to repair and regenerate fractures and small ... -
Drilling Damage in Laminated Polymer Matrix Composites Considering Thermal Efefcts: Experimental and Numerical Analysis
In the present work, drilling induced damage in multi-directional carbon fiber reinforced polymer (MD-CFRP) laminates has been investigated by experimental and numerical approaches. Exit-ply delamination during drilling ... -
Vaned Diffuser Effect on Centrifugal Compressor Performance and Stall
A centrifugal compressor is a mechanical device that helps to achieve higher pressure ratios at lower mass flow rates. It is used in many applications such as turbochargers, cruise missiles, and turbojet engines where ... -
Correlation Between Microstructure and Corrosion Properties of Electrodeposited Nickel and Zinc Based Coatings
Conventional metallic coatings such as Ni and Zn are extensively used in corrosion protection applications. In most studies on the corrosion behavior of metallic coatings, the emphasis is on correlating morphology and ... -
Implicit Gradient Reconstruction for Unstructured Mesh Finite Volume Method
In the present work, an Implicit Gradient Reconstruction (IGR) method is proposed in the context of Finite Volume Methodology (FVM). There are three computationally intensive steps involved in a typical finite volume ... -
Numerical Study of Accelerating Turbulent Boundary Layers
This thesis focuses on the prediction of favourable pressure gradient turbulent boundary layer flows. Particularly, the focus is on mild favourable pressure gradient turbulent boundary layers and relaminarising turbulent ... -
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 ... -
A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ... -
Monitoring and Control of Intermittent Water Distribution Network
Millions of people in low and middle-income countries worldwide receive water only for a small fraction of the time in a day through piped networks. Even though the percentage of the world’s population with access to piped ... -
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units for hydrological classification. They are self-organizing systems whose form, drainage network, ground and channel slopes, channel ... -
Efficient Finite Element-Based Approaches for Solving Potential Flow Problems in Fluids
For many years, fluid flows have been modeled, starting from basic potential flow equations to full Navier-Stokes equations. The complexity of the flow increases as viscous effects, boundary layer, and flow separation are ... -
Classical Approach to Understanding the Impact Dynamics of Hollow Droplets
Compound droplets are utilized in applications ranging from the preparation of emulsion to biological cell printing and additive manufacturing. Here, we report on the impact dynamics of a compound hollow droplet on a ... -
On late stages of transition in round jets
A round jet is one of the simplest canonical axisymmetric free shear flows that occur both in engineering applications and natural phenomena. A laminar-turbulent transition process is inherent to its development involving ... -
An Experimental Investigation of Transitional and Turbulent Channel Flow
This thesis is a comprehensive experimental investigation of transitional and turbulent channel flow in the Reynolds number range of Reτ = 55 − 1559. Towards this objective, a new channel flow facility was designed and ... -
Approaches to Regional Analysis of Hydro-Meteorological Processes and Extremes
Regional analysis of hydrometeorological variables (e.g., evapotranspiration, precipitation), hydrological processes (e.g., runoff), and their extremes (e.g., drought, floods) is essential for various applications. The ...
