Maintaining Underwater Cassie State for Sustained Drag Reduction in Channel Flow
(2018-02-21)Water droplets tend to bead up on rough or textured hydrophobic surfaces by trapping air on the crevices underneath resulting in “Cassie” state of wetting. When a textured hydrophobic surface is immersed in water, the ... -
Measurement And Analysis Of Friction Induced By A Cutting Operation Lubricated By Oil In Water Emulsion
(2013-09-05)The lubricants that are applied during metal cutting acts on the interface between the tool and the nascent surfaces generated by the cutting process. Dispersions of oil in water made using suitable emulsifier(s) are used ... -
Measuring Three-dimensional Deformations of Elastic Ribbons
Experimental techniques to measure and visualize kinematics in structural and solid mechanics range from humble strain gage rosettes to sophisticated digital image correlation methods. This thesis develops a stereo ... -
Mechanics and Mechanisams in Fretting Damage for Stainless Steel and Chromium Carbide Coatings
(2018-04-11)Fretting is a serious concern in many industrial components, specifically, in nuclear industry for the safe and reliable operation of the component/system. Till date, a lot of efforts has already been made to understand ... -
Mechanics of collective cell migration on substrates of different stiffness
Collective cell migration is characteristic in many physiological processes such as wound closure, morphogenesis, and cancer tumour metastasis. Experiments on cell monolayers demonstrated the formation of finger-like ... -
Mechanobiology of cell-substrate interactions
Cell adhesion to substrates is a complex process facilitated by focal adhesion (FA) complexes that help them perform vital cellular functions like migration, growth, and division. Cells probe their surroundings through ... -
Micro-Mechanisms Associated with Friction Stir Welding of Aluminum with Titanium
(2018-01-10)Out of the known aerospace metal and alloys, Aluminium (Al) and Titanium (Ti) are important due to their unique combination of properties, such as strength, ductility and corrosion resistance etc. For these reasons, welding ... -
Micro-PIV Study Of Apparent Slip Of Water On Hydrophobic Surfaces
(2010-07-01)The condition of no relative velocity of fluid past solid is termed as ‘no-slip boundary condition’. This condition is a general observation in fluid mechanics. However, several research groups have recently reported slip ... -
Microstructure Evolution In Semisolid Processing
(2014-09-09)In this thesis, we present an experimental and numerical study of globularization during reheating of thixocast billet having non-dendritic microstructure. The process of reheating is an important step in the semisolid ... -
Microstructure, mechanical behavior, and thermal stability of in-situ polymer-derived ceramic reinforced Al-based composites
Al-based metal matrix composites (MMCs) show a high strength-to-weight ratio which makes them attractive for the aerospace and automobile industries. The reinforcements for the same have conventionally been micron-sized ... -

Modeling Free Surface Flows and Fluid Structure Interactions using Smoothed Particle Hydrodynamics
(2018-06-26)Recent technological advances are based on effectively using complex multiphysics concepts. Therefore, there is an ever increasing need for accurate numerical al-gorithms of reduced complexity for solving multiphysics ... -
Modeling of the Haltere-A Natural Micro-Scale Vibratory Gyroscope
(2018-06-05)Vibratory gyroscopes have gained immense popularity in the microsystem technology because of their suitability to planar fabrication techniques. With considerable effort in design and fabrication, MEMS (Micro-electro-mec ... -
Modeling Of Transport Phenomena In Arteries
(2013-05-23)Atherosclerosis is an arterial disease that occurs due to the build-up of lipids, cholesterol and other substances in the arterial wall, collectively called plaque, leading to narrowing of the vessel lumen and, in time, ... -
Modular Kinematic Analysis Of Planar Linkages
(2009-04-24)This thesis has developed an efficient methodology for automatic kinematic analysis of planar linkages using the concept of modular kinematics. Unlike conventional general purpose kinematic analysis packages where each joint ... -
A Monolithic Finite Element Formulation for Magnetohydrodynamics Involving a Compressible Fluid
This work develops a new monolithic finite-element-based strategy for Magnetohydrodynamics (MHD) involving a compressible fluid based on a continuous velocity-pressure formulation. The entire formula- tion is within a ...
