Aerobreakup of a Polymeric Droplet
Aerobreakup of a liquid droplet refers to the process of breaking the droplet into smaller fragments by subjecting it to a sufficiently high-speed stream of gas (generally air). This process lies at the core of various ... -
Dynamically isotropic Gough-Stewart platform for micro-vibration isolation in spacecraft
Rotating components such as reaction wheels and momentum wheels on spacecraft generate micro-vibrations up to 250 Hz during on-orbit operations. While the use of Gough-Stewart Platforms (GSPs) for six degrees of freedom ... -
Dynamics of Leidenfrost droplets on microtextured substrates
A liquid droplet placed on a heated substrate at temperatures significantly higher than the saturation temperature of the liquid levitates over a thin film of vapor and is termed as a Leidenfrost (LF) droplet. Leidenfrost ... -
Emergence and Propagation of Aerodynamic Instabilities in Centrifugal Compressors with Vaned Diffusers: Effect of Solidity and Stagger
Centrifugal compressors are widely employed in turbochargers and small gas turbines due to their ability to achieve high compression per stage. These compressors consist of a rotating impeller and a static diffuser, which ... -
Energy Loss in Elastic Plastic Low Velocity Impacrt In Presence of Electric Field
Impact phenomena are prevalent in various fields, including the impact between celestial bodies, particle dampers, sports mechanics, and granular media. Impacts between bodies often exhibit inelastic behaviour due to ... -
Experimental and Numerical Studies of Multiturn Multiplane Pulsating Heat Pipes
Embargo up to 15/1/2027 A Pulsating Heat Pipe (PHP) is a wickless meandering capillary tube bent back and forth parallel to itself. PHPs are classified into single and multiturn, closed-loop and open-loop. A single loop ... -
In situ analysis of large strain deformation in tool-workpiece contacts
Large strain plastic deformation is central to manufacturing operations like metal cutting, rolling, and extrusion. Standard approaches for describing and understanding this deformation, such as analytical methods, numerical ... -
In-situ Tribological Experiments to Study - The Effect of Contact Stresses on Raman Scattering
This thesis presents the design, development, and validation of novel instruments that enable in situ micro-Raman spectroscopic measurements at mechanically loaded interfaces: an indentation apparatus for static loading ... -
Insights on the Evaporation and Precipitation of Pathogen-Laden Respiratory Droplets on Inanimate Surfaces
Disease transmission via fluid ejections from infected individuals is a critical public health concern, particularly in high-risk environments like hospitals, public transport, restaurants, and schools. Respiratory droplets ... -
Investigations on Radial Inflow Turbine for Supercritical CO2 Power Cycles
Potential of using supercritical CO2 (sCO2) as a working fluid for the next generation of thermal power plants is being actively pursued by researchers across the world. CO2 has a critical temperature of 31.1 °C and a ... -
Mechanisms and mechanics of mixed-mode (I/II) fracture of magnesium alloys
Magnesium alloys are considered as a desirable substitute for aluminium alloys in automotive structural components due to their high strength-to-weight ratio which is crucial for improving vehicle performance and fuel ... -
Modeling of Supercritical Carbon Dioxide Centrifugal Compressors for Brayton Power Cycles
Due to several perceived advantages, supercritical Carbon dioxide (sCO2) cycles are viewed as potential replacements for steam-based power generation. Their successful deployment depends on several factors - one important ... -
Modelling Cable-driven Continuum Robots and their applications
Flexible robots have been gaining traction in real-world applications over their rigid counterparts for their favourable features such as flexibility, compliance, better manoeuvrability, lightweight construction and ability ... -
Multifunctional Biomaterials based on Polyacrylamide/Hydroxyapatite for magnetic biosensing and Musculoskeletal Repair
