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 ... -
Experimental Study Of Large Angle Blunt Cone With Telescopic Aerospike Flying At Hypersonic Mach Numbers
(2011-04-06)The emerging and competitive environment in the space technology requires the improvements in the capability of aerodynamic vehicles. This leads to the analysis in drag reduction of the vehicle along with the minimized ... -
Experimental Study of Multiphase Flow in the Presence of Raceway in the Packed Beds
The lower part of the iron-making blast furnace is very important for operational stability and productivity of it. It represents a multiphase flow, including a cohesive zone. In order to reduce the coke consumption and ... -
Experimental Study of Patterns in Hydrodynamically Deposited Dispersed Phase of CaCO3 on Surfaces of Straight Cylindrica Silica Tubing
(2018-08-13)Deposition of dispersed phase from flowing dispersions onto a substrate surface is of utmost relevance for various industrial processes like fouling of sparingly soluble salts, such as CaCO3 and CaSO4 in heat exchangers and ... -
Experimental Study Of Plasma Actuator Characteristics And Optimization Of Configuration
(2013-06-26)Plasma actuators are devices which function by creating a discharge in air at atmospheric conditions. These devices have been demonstrated to effectively delay flow separation and enhance the lift- drag characteristics of ... -
Experimental study of sudden expansion in pipe flow
An Experimental Study of Sudden Expansion in Pipe Flow Flow through a sudden expansion, though the simplest and perhaps the earliest problem of fluid flow separation, still leaves much to be understood. The sudden expansion ... -
Experimental study of the flow of granular media through a horizontal screw feeder system
A significant fraction of the materials handled in the chemical, food-processing, and pharmaceutical industries are particulate in nature. Screw feeder systems are often employed in such scenarios to achieve their bulk ... -
Experimental Study On The Impact Of Water Drops On Groove-Textured Surfaces
(2014-09-08)The interaction of a liquid drop with a solid surface is being actively studied to understand practically encountered scenarios such as the impact of fuel spray droplets onto the walls of engine combustion chamber, the ... -
An experimental study on thermoelectric transport at van der Waals interfaces
When two planar atomic or molecular layers are brought to sub-nanometer proximity, they form a van der Waals interface because the van der Waals force forms the dominant attractive force between them. The van der Waals ... -
Experimental, Numerical and Probabilistic Analysis of Reinforced Anchors for Transmission Tower Foundations
The foundations of tall structures such as transmission towers are subjected to loads in three directions coming from wind and other environmental events. The use of anchors for application in transmission tower foundations ... -
