Characterization of a large scale hypersonic shock tunnel and investigation of the effect of roughness on a large cone boundary layer flow
High speed flight is ridden with engineering challenges, some of which have been studied
for decades with only minor improvements. Boundary layer transition to turbulence in
highMach number flow is one such topic, which, ...
An Evaluation of the Mechanical Behavior of some new High Temperature Materials
Two new high-temperature alloy systems have been discovered recently at the Indian
Institute of Science, which form the basis of this thesis. The first alloy system is an
Intermetallic-Intermetallic eutectic composite ...
Development of an efficient domain decomposition algorithm for solving large stochastic mechanics problems
With the growth of computational resources available, demand on the accuracy and speed of
simulation is steeply increasing. Accordingly, accounting for the variabilities in the simulations
plays a pivotal role in taking ...
Experimental Investigations Into Fracture and Fatigue Behavior Of Plain and Reinforced Concrete Beams Using Acoustic Emission Technique
Concrete is the most widely used material in the world for construction of infrastructures and there are quite a few gaps in understanding its behaviour under different loads. Fracture in concrete occurs at pre-existing ...
Micromechanical modeling of fracture and fatigue behavior of cementitious composites
The ubiquitous use of concrete as a construction material in the civil engineering industry
demands a thorough understanding of its failure process under different types of loading.
The composite nature of cementitious ...
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 ...
Liquid Jet in Swirling Cross Flow
Liquid jets in cross flows (JICF) have been an important part of spray research in the last few decades owing to the wide spectrum of applications ranging from agricultural sprays to aircraft gas turbine engines. However, ...
Phononic bandgap engineering in cellular periodic structures and mechanical metamaterials
A methodology has been developed for the computation of phononic band structure of cellular periodic structures, structures with spatially repetitive patterns, using Frequency domain Spectral Finite Element Method along ...
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired
and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this
emergence has been ...
Architecting Conjugated Molecules for Band Gap Engineering & Photostability
Organic photovoltaic (OPV) modules are flexible, light weight, transparent and thin compared to other emerging photovoltaic technologies, making them well-suited for applications ranging from solar windows to fabrics. A ...
