Interaction of bubble(s) and buoyant rigid particles with vortical structures: Towards understanding bubbly turbulent flows
Bubbly turbulent flows occur in many places, such as in chemical reactors and geophysical applications, besides interest from the drag reduction perspective using injected bubbles in a (water) boundary layer. In these ... -
Comprehensive Study on Synthesis and Characterization of Nanocellulose Reinforced Green Composites
Environmental issues caused by the non-biodegradability of synthetic thermoplastics have increased interest in more environmentally friendly alternatives that should be derived from renewable resources. This work focuses ... -
Structure of Turbulent, Swirling Round Jets
The present study deals with the numerical analysis of the effect of the swirl in the self-preservation region of the turbulent round jet. However, a large number of literature exists for the analysis of near-exit regions—very ... -
Control and Safety of Multi-UAV Systems for Collaborative Payload Transportation and Target Tracking
Unmanned aerial vehicles (UAVs) have been widely used in reconnaissance, remote sensing, disaster relief, and agricultural applications. Many applications require multiple UAVs to cooperate to complete the assigned tasks. ... -
A Tropical Survey of Mid-Tropospheric Cyclones, their Classification and Genesis over the Arabian Sea
Middle Tropospheric Cyclones (MTCs) are moist synoptic tropical systems with vorticity maxima in the middle troposphere and weak signature in the lower troposphere. We begin with a tropical survey of MTCs; in South Asia, ... -
Resource Allocation for Natural Disasters using a Game-theoretic Framework
The occurrence of a severe natural disaster causes loss of life and destruction of properties. The overall criticality of the disaster depends on the nature of the disaster and the physical characteristics of the affected ... -
Hyperspectral remote sensing for soil property estimation in the context of spectral mixtures
The implementation of sustainable agricultural, hydrological, and environmental management entails an improved understanding of soil properties and its conditions at increasingly finer resolutions. In this context, the ... -
Monte Carlo simulations of Electric Double Layer Capacitors with aqueous electrolytes
Electric double layer capacitors (EDLCs) also known as supercapacitors are a category of energy storage devices that are known for their remarkable power delivery (upto 1000KW/kg). The energy storage is through physical ... -
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 ... -
