Influence of Surface Topography and Roughness on Lubrication, Friction and Scuffing in High Hardness Steels
In tribology engineering, friction control is a significant challenge. The interacting surfaces of mechanical components are typically designed for best efficiency during tribological operations and are primarily achieved ...
Numerical and Experimental Investigation of Mixed-mode Fracture Behavior of Basal Textured Magnesium Alloys
Magnesium alloys are finding tremendous applications in automobile and aerospace industries owing to their low density, high specific strength, good machinability and damping characteristics. However, their structural ...
Turbulent Free Convection Over Horizontal Surfaces
This thesis deals with turbulent free convection in a horizontal fluid layer above a heated
surface. The work can be roughly divided into two parts. In the &st part a model
is proposed for the near wall dynamics in ...
Measuring Three-dimensional Deformations of Elastic Ribbons
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 ...
Supercritical CO2 Power Cycles and Turbomachinery Development for Renewable Energy and Waste Heat Recovery
Supercritical carbon dioxide (sCO2) power cycles have transitioned from the kilowatt level pilot facilities to the megawatt level demonstration plants. Theoretical studies and commercial benefits associated with sCO2, such ...
Flow Over A Circular Cylinder With A Flexible Splitter Plate
(2010-07-08)
Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ...
Steady Sedimentation of Particles in Long Vertical Tube and Effect of End Boundary Conditions on Convective Motion
Sedimentation – settling of particles in a fluid- is observed in nature like rain droplets and dust particles in the atmosphere, and in a variety of industrial processes, like to clarify liquid as well as separate particles ...
Mechanics of collective cell migration on substrates of different stiffness
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 ...
Stability of wall-bounded compressible shear flows
In this work, the linear stability of compressible shear flows in channels and pipes are studied. A steady fully-developed laminar flow of an ideal gas, driven in a channel and a pipe by a constant body acceleration, is ...
ALE-based Monolithic Finite Element Strategies for Fluid Structure Interaction Problems
Fluid-structure interactions (FSI) represent a class of engineering problems which involve a two-way coupling between the solid motion and the fluid flow. The deformation of the solid caused by the fluid forces at the ...
