On late stages of transition in round jets
A round jet is one of the simplest canonical axisymmetric free shear flows that occur both
in engineering applications and natural phenomena. A laminar-turbulent transition process
is inherent to its development involving ...
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units
for hydrological classification. They are self-organizing systems whose form, drainage
network, ground and channel slopes, channel ...
A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ...
Global and combined global-local response sensitivity analyses of uncertain structures based on model distance measures
The work reported in this thesis is in the area of global response sensitivity analysis (GRSA) of engineering systems in which the uncertainties associated with external actions and/or system parameters need to be explicitly ...
GRACE-based Assessment of Climatic Controls on Hydrological Variables
Anthropogenic climate change is now well-established and is expected to have serious implications on Terrestrial Hydrologic cycle. This inspired scientific investigation to assess the impact of various climatic processes ...
Bearings-Only Information Based Guidance Law for Trajectory Shaping Applications
Munitions like projectiles and artillery mortars follow ballistic trajectory to hit the target. However, unguided munitions may miss the target due to external disturbances or errors in aerodynamic modeling. A guided ...
Correlation Between Microstructure and Corrosion Properties of Electrodeposited Nickel and Zinc Based Coatings
Conventional metallic coatings such as Ni and Zn are extensively used in corrosion protection applications. In most studies on the corrosion behavior of metallic coatings, the emphasis is on correlating morphology and ...
Implicit Gradient Reconstruction for Unstructured Mesh Finite Volume Method
In the present work, an Implicit Gradient Reconstruction (IGR) method is proposed in the
context of Finite Volume Methodology (FVM). There are three computationally intensive steps
involved in a typical finite volume ...
Numerical Study of Accelerating Turbulent Boundary Layers
This thesis focuses on the prediction of favourable pressure gradient turbulent boundary layer flows. Particularly, the focus is on mild favourable pressure gradient turbulent boundary layers and relaminarising turbulent ...
Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude. The most widely ...
