Experiments On Rolling Sphere Submerged In An Incompressible Fluid
(2016-09-15)Experiments are done using a smooth solid rigid homogeneous acrylic sphere rolling on an inclined plane which is submerged in water. The motivation for these experiments comes from a need to understand a class of solid-fluid ... -
Exploration And Assessment of HCCI Strategies for a Multi-Cylinder Heavy-Duty Diesel Engine
(2017-10-17)Homogeneous Charge Compression Ignition (HCCI) combustion is an alternative combustion mode in which the fuel is homogeneously mixed with air and is auto-ignited by compression. Due to charge homogeneity, this mode is ... -
Externally Induced Instabilities in Contactless Functional Droplets
Many natural and technological processes involve spray or cluster of droplets which are subjected to chaotic external environment. Study of the behavior of a single droplet is therefore crucial to understand the dynamics ... -
Fabrication and Characterization of Optomechanical Devices
Silicon photonics is a promising platform for photonic devices and circuits, largely driven by advanced complementary metal-oxide-semiconductor (CMOS) processing technology. An extremely crucial component for a photonic ... -
Feasible and Intrinsic Kinetoelastostatic Maps for Compliant Mechanisms
(2018-03-06)Despite many advances in the design methods for compliant mechanisms, it is still not possible to know if a set of user-specifications has a solution. Furthermore, practical considerations such as failure limits and ... -
Finite Element And Experimental Studies On Fracture Behavior Of Bulk Metallic Glasses
(2011-01-19)The objective of this thesis is to study the fracture behavior of bulk metallic glasses. For this purpose, detailed finite element investigation of the mode I and mixed mode (I and II) stationary crack tip fields under ... -
A Finite Element Investigation Of Brittle Fracture During Spherical Nanoindentation Of Thin Hard Films
(Indian Institute of Science, 2006-12-14)Hard ceramic films of micrometric thickness deposited on a soft metallic substrate have ushered in a new era in the fabrication of structural, tribological, microelectronic and optical components. The mechanical performance ... -
Flow Acoustic Analysis Of Complex Muffler Configurations
(2013-06-21)A theoretical study has been carried out on different methods available to analyze complex mufflers. Segmentation methods have been discussed in detail. The latest two port segmentation method has been discussed and employed ... -
Flow and Forces on Rigid and Flexible Plates in Unsteady Rotational Motion
The swimming motion of fishes have long fascinated scientists and engineers. Over the past few decades, researchers have studied physical models mimicking the tail beat of fishes in an effort to extract key physical ... -
Flow and Windage Heating in Labyrinth Seals
(2017-11-24)The ability to quantify leakage flow and windage heating for labyrinth seals with honeycomb lands is critical in understanding gas turbine engine system performance and predicting its component lifes. Variety of labyrinth ... -
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 ... -
Force Measurements On Rigid And Flexible Oscillating Foils
(2013-10-04)In the present work, we experimentally study thrust generation from sinusoidally pitched rigid and flexible foils immersed in a uniform flow. The flexible foils are made by attaching a flexible flap of known flexural ... -
Force-Amplifying Compliant Mechanisms For Micromachined Resonant Accelerometers
(2013-04-04)This thesis work provides an insight into the design of Force-amplifying Compliant Mechanisms (FaCMs) that are integrated with micromachined resonant accelerometers to increase their sensitivity. An FaCM, by mechanically ... -
Frequency-Tuning and Dynamic Simulation of Electrostatically Actuated Beams
(2018-01-03)The resonance frequency of electrostatically actuated micromachined beams can be tuned substantially by applying a DC voltage bias, first by decreasing the frequency until the onset of pull-in and then by increasing it by ... -
Fuel Filim Visualization And Measurement In The Inlet Manifold Of A Carbureted Spark-Ignition Engine
(2013-10-01)In order to meet future emission norms for small carbureted SI engines, such as those used on motorcycles in India, there is a need to study mixture preparation, specifically the two-phase flow exiting the carburetor and ... -
Fundamental Studies On Tribological Response Of Titanium And Copper
(2007-08-22)Friction and wear have been observed m mechanical systems when there is a relative motion between two solid bodies Friction mainly results in loss of energy and wear results in matenal loss The proper understanding of ...
