Maintaining Underwater Cassie State for Sustained Drag Reduction in Channel Flow

Dilip, D (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

Anirudhan, P (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 ...

Measurement And Prediction Of Four-pole Parameters And Break-out Noice Of Mufflers

Narayana, T S (2011-08-17)

Measurement Of Hydrodynamic Forces On Axisymmetric Bodies Using A Towing Tank

Krishna Kumar, R. (2011-11-09)

Measuring Three-dimensional Deformations of Elastic Ribbons

Gupta, Kishan Kumar

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

Chaudhry, Vijay (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

Dey, Suvakash

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 ...

Mechanisms and mechanics of mixed-mode (I/II) fracture of magnesium alloys

Baruah, Dhrubjyoti

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 ...

Mechanobiology of cell-substrate interactions

Jaddivada, Siddhartha

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 ...

Medial Axis Transform For The Prediction Of Shrinkage And Distortion In Castings

Ramanathan, M (2013-07-25)

Micro-Mechanisms Associated with Friction Stir Welding of Aluminum with Titanium

Kar, Amlan (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

Asthana, Ashish (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

Apoorva, * (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

Pariyar, Abhishek

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 ...
