Flexible Nanostructured Hydrogen Sensors
Hydrogen is rapidly emerging as a key energy carrier and industrial feedstock in the global transition to cleaner energy systems. However, due to its high diffusivity and flammability, even minor leaks can result in ... -
FLIPP-NAAT: A paper-based LAMP assay for point-of-care TB detection
Molecular diagnostic techniques like polymerase chain reaction (PCR) revolutionized the world of healthcare. Instead of waiting for infectious agents to physically grow as in conventional culture-based tests, genetic ... -
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 ... -
Flow Acoustic Analysis Of Complex Muffler Configurations
(2013-06-21)A theoretical study has been carried out on different methods available to analyze complex mufflers. Segmentation methods have been discussed in detail. The latest two port segmentation method has been discussed and employed ... -
Flow and Forces on Rigid and Flexible Plates in Unsteady Rotational Motion
The swimming motion of fishes have long fascinated scientists and engineers. Over the past few decades, researchers have studied physical models mimicking the tail beat of fishes in an effort to extract key physical ... -
Flow and structure of dense granular materials
Granular materials are frequently encountered in our daily lives and are widely processed forms of matter in various industries. Despite decades of research, the mechanical behavior of granular materials is not well ... -
Flow and Windage Heating in Labyrinth Seals
(2017-11-24)The ability to quantify leakage flow and windage heating for labyrinth seals with honeycomb lands is critical in understanding gas turbine engine system performance and predicting its component lifes. Variety of labyrinth ... -

This thesis presents an extensive and systematic study of the free and submerged flow characteristics of rectangular and trapezoidal finite crest width weirs and triangular profile weirs. Aspects studied include the ... -
Flow characteristics of sharp-edged orifices,quadrant-edged orifices and nozzles
This thesis presents an integrated study of flow past sharp-edged orifices, quadrant-edged orifices and long radius nozzles, covering different aspects such as metering characteristics, loss characteristics and flow ... -
Flow Over A Circular Cylinder With A Flexible Splitter Plate
(2010-07-08)Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ... -
Fluid-Elastic Interactions in Flutter And Flapping Wing Propulsion
(2017-10-06)This study seeks to understand the interplay of vorticity and elasto-dynamics that forms the basis for a fluttering flag and flapping wing propulsion, and factors that distinguish one from the other. The fluid dynamics is ... -
Flutter Identification and Aeroelastic Stability during Wake Penetration
Demonstration of utter stability over the design envelope and identi fication of safe ight envelope is a prerequisite for operational clearance of any new aircraft design. An important step involved in flight flutter ... -
Flutter Susceptibility Assessment of Airplanes in Sub-critical Regime using Ameliorated Flutter Margin and Neural Network Based Methods
(2018-02-17)As flight flutter testing on an airplane progresses to high dynamic pressures and high Mach number region, it becomes very difficult for engineers to predict the level of the remaining stability in a flutter-prone mode and ... -
Foaming of Surface Waterbodies: A Comprehensive Study on Causes, Persistence, Seasonality, and Mitigation Strategies
Foaming waterbodies have emerged as a significant global concern due to their adverse effects on aquatic ecosystems, offensive odour emissions, disruption of daily activities in nearby areas, and visual unpleasantness. ... -
Force Measurements On Rigid And Flexible Oscillating Foils
(2013-10-04)In the present work, we experimentally study thrust generation from sinusoidally pitched rigid and flexible foils immersed in a uniform flow. The flexible foils are made by attaching a flexible flap of known flexural ... -
Force-Amplifying Compliant Mechanisms For Micromachined Resonant Accelerometers
(2013-04-04)This thesis work provides an insight into the design of Force-amplifying Compliant Mechanisms (FaCMs) that are integrated with micromachined resonant accelerometers to increase their sensitivity. An FaCM, by mechanically ... -
Formation and Maintenance of the Southern Bay of Bengal Cold Pool
(2018-06-11)Around Sri Lanka and to the south of India sea surface temperatures (SST) are cooler compared to the surrounding region during summer monsoon. This region where SSTs are relatively cooler is known as the cold pool. Owing ... -
