Matrix cracking in polymer matrix composites under static and fatigue loading
Matrix cracking is the first and most dominant mode of damage in polymer matrix composite (PMC) laminates resulting in significant stiffness degradation under static and fatigue loading. Matrix crack evolution and its ...
Design of Planar Supersonic Wind Tunnel Nozzle
This thesis revisits the design of a planar supersonic nozzle for a supersonic wind tunnel using
the method of characteristics (MOC) and Computational Fluid Dynamics (CFD). While design
of a converging-diverging (CD) ...
Lattice Boltzmann Relaxation Schemes for High Speed Flows
The lattice Boltzmann method (LBM) has emerged as a highly efficient model
for the simulation of incompressible
flows in the last few decades. Its extension to
compressible
flows is hindered by the fact that the ...
Development of Tubular Solar Receiver with Supercritical Carbon Dioxide as Working Fluid
Over the past decade, solar powered supercritical carbon dioxide (s-CO2) based Brayton
cycle has been identified as a promising candidate due to its potentially high cycle efficiency
(50%, for turbine inlet temperatures ...
Supporting Environmentally-benign Design at Conceptual Stage
An ‘environmentally-benign design’ is defined as that which causes little or no harm to the natural environment and may
be achieved by reducing the environmental impact of the design solutions conceptualised, to be ...
Microscale mechanical behaviour of ceramic matrix composites considering processing e ects
The current work explores the phenomenon of microscale damage mechanism driven quasi-
ductile behaviour of C/BN/SiC ceramic matrix composite (CMC) at the microscale focusing
on process-microstructure-property correlations. ...
Design and development of lateral force-controlled tribosystems
In a tribo-system, the frictional resistance during a sliding process depends on several parameters. These parameters include the interacting materials, their surface topography, contact conditions such as normal load, ...
Towards metal additive manufacturing using alternate powders
Metal powders are predominantly produced using processes derived from atomization, which, apart from being highly energy intensive, are also inflexible and very material specific. These limitations are particularly acute ...
Studies on Two-Stage Air-Cooled Silica gel + Water Adsorption Cooling System
Adsorption cooling systems are evolving as promising complements to conventional vapor compression refrigeration (VCR) systems because of their ability to utilize low-grade heat sources such as industrial waste heat, solar, ...
