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 ...
Numerical Studies on Plastic Deformation, Notch Sensitivity and Fracture Behavior of Bulk Metallic Glasses and Composites
Bulk metallic glasses (BMGs) exhibit attractive properties such as high strength and resilience. However, they display negligible tensile ductility due to catastrophic crack propagation inside a dominant shear band (SB). ...
Breakout Noise From The Coupled Acoustic-Structural HVAC Systems
(2010-07-19)
Noise control in the heating, ventilation and air-conditioning (HVAC) systems is one of the critical design parameters in measuring the occupant comfort. The noise generated by air-handling units propagates through the ...
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired
and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this
emergence has been ...
Unsteady Two Dimensional Jet with Flexible Flaps at the Exit
(2017-11-13)
The present thesis involves the study of introducing passive exit flexibility in a two dimensional starting jet. This is relevant to various biological flows like propulsion of aquatic creatures (jellyfish, squid etc.) and ...
Tribology Of Aluminium Alloys Against Steel Under Boundary Lubricated Condition
(2009-04-15)
Aluminium silicon alloy has been found to be advantageous in many automobile components like pistons, cylinders, brakes and clutches. The main objective in using these alloys is to obtain lightweight and low friction ...
Experimental and Numerical Investigation of an Evaporating Meniscus in a Capillary Slot : Microscale and Pore Scale Studies
(2018-08-09)
An evaporating meniscus formed by a wetting °uid in a heated capillary slot with capillary driven °flow is numerically and experimentally investigated at the microscale and pore scale.
In the microscale analysis, the ...
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 ...
Turbulent Mixed Convection
(Indian Institute of Science, 2006-08-28)
Turbulent mixed convection is a complicated flow where the buoyancy and shear forces compete with each other in affecting the flow dynamics. This thesis deals with the near wall dynamics in a turbulent mixed convection ...
Investigations On High Rayleigh Number Turbulent Free Convection
(Indian Institute of Science, 2005-08-31)
High Rayleigh number(Ra) turbulent free convection has many unresolved
issues related to the phenomenology behind the flux scaling, the
presence of a mean wind and its effects, exponential probability
distribution ...
