Experimental Studies on Extremely Small Scale Vibrations of Micro-Scale Mechanical and Biological Structures
(2018-05-14)Experimental vibration analysis of mechanical structures is a well established field.Plenty of literature exists on macro scale structures in the fields of civil, mechanical and aerospace engineering, but the study of ... -
Experimental Studies on Gaseous Mixing in a Low Area Ratio Rectangular Supersonic Confined Jet
When a supersonic jet passes through a confined passage, it is called as supersonic confined jet. They are encountered in many aerospace applications such as supersonic ejectors, supersonic mixers/purgers, and thrust ... -
Experimental Studies on Methanol Sprays for IC Engine Applications
In this work, studies have been conducted on sprays of methanol and its emulsions with diesel towards assessing the potential of methanol as an alternative fuel for IC engines. Methanol can be used in compression ignition ... -
Experimental Studies on Shock-Shock Interactions in Hypersonic Shock Tunnels
(2017-12-16)Shock-shock interactions are among the most basic gas-dynamic problem, and are almost unavoidable in any high speed light, where shock waves generating from different sources crosses each other paths. These interactions ... -
Experimental studies on Soot and Particulate reduction in Heavy Fuel Oil Combustion
Heavy fuel oil (HFO) is extensively used in industrial burners and marine engines. HFO droplet combustion gives rise to carbon particulates generated by pyrolysis, which are called cenospheres. There is a current hypothesis ... -
Experimental studies on swirling flows at vertically upward intakes
The experimental investigations presented in this thesis are concerned with the aspects of sump geometry and sump parameters, which govern the flow conditions at vertically upward intakes. Detailed studies are made to ... -
Experimental Studies on the Effect of an Upstream Periodic Wake on a Turbulent Separation Bubble
(2018-06-26)The object of the present work is to experimentally study the case of a turbulent boundary layer subjected to an Adverse Pressure Gradient (APG) with separation and reattachment. The effect of unsteadiness on turbulent ... -
Experimental studies on the fracture and fatigue failure processes under direct tension in quasi-brittle materials - Graphite and Concrete
Abstract Fatigue phenomenon is a gradual, permanent, micro structural change that takes place in a material due to the application of repeated loading. In the case of quasi-brittle materials like graphite and concrete, ... -
Experimental Studies on The Mechanical Behaviour of Cohesive Frictional Granular Materials
(2017-09-26)Thss thesis presents the results of an experimental programme on the static mono-tonic response of cohesive-frictional granular materials. The purpose of this experimental programme was to gain insight into the mechanical ... -
Experimental studies on travelling bubble cavitatin noise
An effectively controlled uniform travelling bubble cavitation was made possible at almost all freestream conditions by seeding the flow with artificial nuclei generated by electrolysis within the boundary layer of three ... -
Experimental study of endwall flow in a compressor cascade
Improvement in calculating methods for end?wall boundary layers of blade rows can only come about by a greater understanding of the physics of the flow from which realistic models can be built of the terms that go into ... -
Experimental Study of Flow Past a Circular Cylinder with a Flexible Splitter Plate
(2018-01-04)A circular cylinder is a geometrically simple bluff body that occurs in various practical applications. As with any bluff body, it exhibits large drag forces and a strong fluctuating lift force, both related to the strong ... -
An Experimental Study Of Instabilities In Unsteady Separation Bubbles
(Indian Institute of Science, 2007-06-11)The present thesis is an experimental study of some aspects of unsteady two dimensional boundary layers subject to adverse pressure gradient. An adverse pressure gradient usually leads to boundary layer separation or an ... -
Experimental Study of Isolator Shock Trains in Confined Co-flowing Supersonic Streams
Futuristic high Mach number flight systems using advanced air-breathing propulsion technologies typically have multiple flow paths with supersonic flows that merge before exiting the vehicle. The supersonic-supersonic ... -
