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 ... -
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 Modeling Of Constrained Piezoelectric Thin Films For Structural Health Monitoring
(2010-01-01)The behaviour of a free-standing thin film differs from that of a film surface-bonded or embedded due to the boundary constraints. A general dearth of analytical models, in regard to prediction of the operational competence ... -
On the Contribution of the Launch Platform towards Acoustic Environment of a Launch Vehicle at Lift-off
A launch vehicle experiences intense acoustic loading in the initial phase of its lift-off due to the noise generated by the rocket exhaust. This affects the launch vehicle structure in addition to sensitive payloads and ... -
On The Effect Of Material Uncertainty And Matrix Cracks On Smart Composite Plate
(2017-02-22)Recent developments show the applications of smart structure in different engineering fields. Smart structures can be used for shape and vibration control, structural health monitoring etc. Smart materials can be integrated ... -
On The Reduction Of Drag Of a Sphere By Natural Ventilation
(Indian Institute of Science, 2005-07-08)The problem of bluff body flows and the drag associated with them has been the subject of numerous investigations in the literature. In the two-dimensional case, the flow past a circular cylinder has been most widely studied ... -
On the Structure and Propagation of Premixed Flames in Turbulence
Turbulence interacts with flames over a multitude of lengthscales and timescales. These interactions are nonlinear and are ubiquitous, for example, in propulsion engines operating in space, air, land, and sea. ... -
On Three Dimensional High Lift Flow Computations
(2018-02-18)Computing 3D high lift flows has been a challenge to the CFD community because of three important reasons: complex physics, complex geometries and large computational requirements. In the recent years, considerable progress ... -
On Viscous Flux Discretization Procedures For Finite Volume And Meshless Solvers
(2009-04-29)This work deals with discretizing viscous fluxes in the context of unstructured data based finite volume and meshless solvers, two competing methodologies for simulating viscous flows past complex industrial geometries. ... -
