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 ... -
Observed Subseasonal Variability Of Temperarture And Salinity In The Tropical Indian Ocean
(2013-06-10)Subseasonal variability of tropical Indian Ocean sea surface temperature is thought to influence the active-break cycle of the Asian monsoon. There are several open questions related to the role of surface fluxes, large-scale ... -
An Ocean General Circulation Model Study Of The Arabian Sea Mini Warm Pool
(2009-07-17)The most important component of the climate system over the Indian Ocean region is the southwest monsoon, which dictates the life and economy of billions of people in the tropics. Being a phenomena that involves interaction ... -
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 a Few Non-Classical Perspectives in Solid Mechanics
Postulates in solid mechanics can be broadly classified into three groups describing the geometry of a configuration, mechanical equilibrium and thermodynamics of the deformation process. The geometry defined on a configuration ... -
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 late stages of transition in round jets
A round jet is one of the simplest canonical axisymmetric free shear flows that occur both in engineering applications and natural phenomena. A laminar-turbulent transition process is inherent to its development involving ... -
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 analysis of axially loaded Euler-Bernoulli beam using Galerkin, Fourier transform, and Lie symmetry approach
The beam with axial load is one of the fundamental models in the field of physics and engineering. The applications of this model span from a guitar string to the rotating blade of a helicopter. It has an important role ... -
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 creep behaviour of Ni based solid solution alloys from binary to quaternary
On the creep behavior of Ni based solid solution alloys from binary to quaternary A power-law relationship between the steady state strain rate (𝜀̇) and imposed stress (σ) is well established so that the 𝜀̇∝𝜎^𝑛, at a ... -
On the development of Fe-containing high entropy alloys with improved strength at high temperatures
The emergence of new multicomponent high entropy alloys (HEA) has opened up new avenues for development of high performance materials for structural applications [1]. Among all of them, the precipitation strengthened HEAs ... -
On the development of low mass density gamma strengthened Co-based superalloys
The work herein aims at developing new class of low mass density gamma-strengthened Co-based superalloys with good solvus temperature through systematic addition of Cr into the Co-Ni-Al- Mo-Ta based superalloy. The present ... -
On the development of sensible heat storage for concentrated solar power applications: Thermo-fluid management and materials
Sensible heat storages have extensive use in thermal energy deployment, including concentrated solar power (CSP) applications. Usually, CSP pants demand various techno-economic features in sensible heat storage, such as ... -
