Tribology Of Combustion Generated Soot
(2016-11-19)
Soot is a carbonaceous materials produced as a result of incomplete combustion of fuels (gasoline, diesel, etc). At the present level of automobile technology, emission of soot from combustion in diesel engine appears to ...
Studies On Fuel-Air Stratification And Combustion Modelling In A CNG-Fuelled Engine
(2016-11-19)
In-cylinder fuel-air mixing in a compressed natural gas (CNG)-fuelled, single-cylinder, spark-ignited engine is analysed using a transient three-dimensional computational fluid dynamic model built and run using STAR-CD, a ...
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 ...
High Reynolds Number Flow Over A Backward-Facing Step
(2016-06-21)
Flow separation and reattachment happens in many fluid mechanical situations occurring in engineering applications as well as in nature. The flow over a backward-facing step represents a geometrically simple flow situation ...
Design And Analysis Of Flexible Beam Platform As Vibration Isolator For Space Applications
(2016-10-20)
Spacecrafts are generally equipped with high precision optical and other sensor payloads. The structures of most of the spacecrafts are light-weight, flexible and have low damping. Vibrations are often induced in the ...
Study Of Solidification And Microstructure Produced By Cooling Slope Method
(2016-05-05)
In most casting applications, dendritic microstructure morphology is not desired because it leads to poor mechanical properties. Forced convection causing sufficient shearing in the mushy zone of the partially solidified ...
Air-Assited Atomization Strategies For High Viscosity Fuels
(2016-02-25)
Atomization of fuel is an important pre-requisite for efficient combustion in devices such as gas turbines, liquid propellant rocket engines, internal combustion engines and incinerators. The overall objective of the present ...
Studies In The Dynamics Of Two And Three Wheeled Vehicles
(2016-09-09)
Two and three-wheeled vehicles are being used in increasing numbers in many emerging countries. The dynamics of such vehicles are very different from those of cars and other means of transportation. This thesis deals with ...
Study Of Multiple Asperity Sliding Contacts
(2016-06-18)
Surfaces are rough, unless special care is taken to make them atomically smooth. Roughness exists at all scales, and any surface-producing operation affects the roughness in certain degrees, specific to the production ...
Dynamics Of Cricket Song Towards Nature-inspired MEMS Speakers
(2016-09-15)
The clever designs of natural transducers are a great source of inspiration for man-made systems. At small length scales, there are many transducers in nature that we are now beginning to understand and learn from. Here, ...
