Nonequilibrium wake flows
In order to study the memory of the larger eddies in turbulent shear flow, experiments have been conducted on plane turbulent wakes subjected to external pressure gradients. In some of these experiments the pressure gradient ... -
Nonlinear mode theory of shear flow development
The major part of this thesis is concerned with the description of a new technique for analysing the development of shear layers (particularly in free flows). A principal feature of this method is the expansion of the ... -
Nonlinear Structural Analysis Using Integrated Force Method

Novel Finite Element Formulations For Dynamics Of Acoustic Fluids
(2013-05-02)Fluid-structure interaction (FSI) as the name suggests, is the study of dynamic interaction of both fluid and structure motions. Fluid-structure interaction exists in almost all engineering and science fields. Moreover, ... -
Novel, Robust and Accurate Central Solvers for Real, Dense and Multicomponent Gases
The nonlinear convection terms in the governing equations of inviscid compressible fluid flows are nontrivial for modelling and numerical simulation. The traditional Riemann solvers, which are strongly dependent on the ... -
Numerical methods for non-homogeneous hyperbolic conservation laws
The numerical simulation of hyperbolic conservation equations has reached a level of maturity with the development of several efficient numerical methods in the past three decades. The same level of success is not present ... -

Numerical Simulations Of Axisymmetric Near Wakes At High Reynolds Numbers
(2009-03-13)The flow past the needle of a Pelton turbine injector is an axisymmetric wake embedded in a round jet. The wake does not fully relax to yield a uniform velocity jet due to the short distance between ... -
Numerical solution of non-classical beam and plate theories using di erential quadrature method
For effcient design of the nano/micro scale structural systems, detailed analysis and through understanding of size-dependent mechanical behaviour at nano/micro scale is very critical. Various approaches have been used ... -
Numerical Studies on the Effect of Core Metal Type and Thickness on the Mechanical Behaviour of Fiber Metal Laminates
Fiber Metal Laminates are advanced materials that combine the properties of metals with Fiber Reinforced Plastics to attain enhanced mechanical performance. The desired mechanical properties can be achieved by hybridizing ... -
Numerical Study of Accelerating Turbulent Boundary Layers
This thesis focuses on the prediction of favourable pressure gradient turbulent boundary layer flows. Particularly, the focus is on mild favourable pressure gradient turbulent boundary layers and relaminarising turbulent ... -
A Numerical Study of Changes to Flow Organization and their Prognostic Measures
(2018-05-23)Flow induced self-oscillations cause acoustic pressure oscillations of large amplitude in pipe flows. If Reynolds number is treated as a parameter, these floinduced oscillations occur only at discrete and critical values ... -
Numerical Study Of Low Mach Number Conjugate Natural Convection And Radiation In A Vertical Annulus
(2010-07-23)The problem of low Mach number (non-Boussin´esq) conjugate laminar natural convection combined with surface radiation in a vertical annulus with a centrally located vertical heat generating rod is studied numerically, ... -
A Numerical Study On Absolute Instability Of Low Density Jets
(Indian Institute of Science, 2006-07-20)A spectacular instability has been observed in low density round jets when the density ratio of jet fluid to ambient fluid falls below a threshold of approximately 0.6. This phenomenon has been observed in non-buoyant jets ... -
Odor Source Localization Using Swarm Robotics
(2010-06-02)Locating an odor source in a turbulent environment, an instinctive behavior of insects such as moths, is a nontrivial task in robotics. Robots equipped with odor sensors find it difficult to locate the odor source due to the ... -
On Flow Physics of Spinning Samaras
A particular form of winged seed (samara) dispersal technique adopted by nature uses autorotative (unpowered rotation of the wing generating thrust force against gravity) descent; for eg. in Maple and Mahagony trees. ... -
On High-Speed Curved Compression Ramp Air Intakes
A scramjet, i.e., a supersonic combustion ramjet, is an air-breathing engine that enables sustained atmospheric flight in the hypersonic regime. It consists broadly of four key components: the air intake, isolator, combustor, ...
