Response of Granular Materials Towards Blast Loading
Granular media, such as sand, soil, and rocks, are commonly encountered in various engineering
and geotechnical applications, and their response to blast loading is of significant interest. In this
master’s thesis, the ...
Investigating Instability Mitigation through Flame Oscillator Synchronization
Stringent emission regulations for reducing NOx and soot emissions are driving gas turbine
combustors manufacturers to adopt lean premixed combustion technology. However, the
rich dynamics of turbulent, lean premixed ...
Discrete Velocity Boltzmann Schemes with Efficient Multidimensional Models
Traditional CFD algorithms have achieved a high degree of sophistication for modelling fluid flows in the past five decades. This sophistication can be seen clearly in one dimensional modelling, with a wide variety of ...
Robust Station-keeping and High-Precision Attitude Control for a Spacecraft on Sun–Earth L1 Halo Orbit
The halo orbits around the Sun-Earth L1 Lagrange point form an ideal location for deploying a solar observation spacecraft as they offer uninterrupted, long-duration visibility of the Sun. However, the complex orbital and ...
Prediction of multi-physical properties of fibre-reinforced composites using deep learning
This work develops a convolutional neural network (CNN) based surrogate model for simultaneous multi-physical property prediction from the binary images of fibre-reinforced composites representative volume elements (RVEs). ...
Characterization and Control of Boundary Layer Transition Caused by Distributed Surface Roughness
Distributed roughness occurs over a variety of aerodynamic surfaces such as wind-/gas-turbine blades and aircraft wings in the form of dust, insect strikes, fouling or icing. The disturbances introduced by the roughness ...
Vorticity and scalar transport in turbulent round jets with and without heating
The round turbulent jets are ubiquitous in both natural and engineered systems such as clouds,
engine exhausts, chimney plumes, and respiratory flows. We aimed to understand the vorticity and
scalar transport in turbulent ...
Longitudinal Acceleration-based Variable Speed Bio-inspired Guidance Law
Most analyses of existing interceptor guidance laws assume the interceptor speed to be constant, which simplifies mathematical analysis and enhances predictability in interception characteristics. In reality, this is not ...
Design and Performance Analyses of Osculating Cone Waveriders
Modern mission requirements for long-range maneuverable hypersonic vehicles for
space, military, and transportation applications necessitate vehicle design innovations.
The primary challenges that a hypersonic vehicle ...
Interfacial oscillations and atomization of liquid jets from non-circular orifices
Understanding the flow behaviour of liquid jets discharging from orifices is essential for several applications such as fuel spraying, ink-jet printing, aerosol devices in pharmaceutical industries, micro-machined fuel ...
