Unsteady Flow Field Downstream Of A Sudden Expansion
(2009-04-02)
Separating and reattaching flows are important in a large number of engineering configurations. The flow through a sudden expansion (backward-facing step) represents a conceptually simple case of this class of flows and hence ...
The Effect Of Viscosity On The Erosion Of Gradient- Zone In A Laboratory Solar Pond
(Indian Institute of Science, 2006-08-24)
Double diffusive phenomena occur in many natural systems and in a variety of engineering applications, such as solar ponds. In a solar pond, the erosion of gradient zone due to convection and diffusion is the main cause ...
Creation of an Orderly Jet and Thrust Generation in Quiescent Fluid from an Oscillating Two-dimensional Flexible Foil
(2018-02-22)
In nature, many of the flapping wings and fins in swimming and flying animals have various degrees of flexibility with strong and coupled solid-fluid interactions between the structure and the fluid. In most cases, the ...
Studies on the Design of Novel MEMS Microphones
(2018-02-17)
MEMS microphones have been a research topic for the last two and half decades. The state-of-the-art comprises surface mount MEMS microphones in laptops, mobile phones and tablets, etc. The popularity and the commercial ...
A Study of Mode Dependent Energy Dissipation in 2D MEMS Resonators
(2018-02-25)
With the advent of micro and nano electromechanical systems (MEMS/NEMS), there has been rapid development in the design and fabrication of sensitive resonant sensors. Sensitivity of such devices depends on the resonant ...
Studies on Multiphase, Multi-scale Transport Phenomena in the Presence of Superimposed Magnetic Field
(2018-02-28)
Multiphase transport phenomena primarily encompass the fundamental principles and applications concerning the systems where overall dynamics are precept by phase change evolution. On the other hand, multiscale transport ...
Maintaining Underwater Cassie State for Sustained Drag Reduction in Channel Flow
(2018-02-21)
Water droplets tend to bead up on rough or textured hydrophobic surfaces by trapping air on the crevices underneath resulting in “Cassie” state of wetting. When a textured hydrophobic surface is immersed in water, the ...
Development of New High Strength Alloy in Cu-Fe-Si System through Rapid Solidification
(2018-02-21)
Copper based alloys play important role in high heat flux applications, particularly in rocket technology, the liner of the combustion chamber, and also in other heat transfer vessels. In these applications, one needs ...
Investigation of Graphene Oxide Based Multilayered Capsules/Films for Drugs Delivery And Antimicrobial Applications
(2018-04-24)
Polyelectrolyte multilayer capsules fabricated by layer-by-layer (LbL) self-assembly technique consistsing of core-shell structure have emerged as potential drug delivery systems along with their applications in micro-reactors, ...
Microstructural Developments and Mechanical Properties of Electroless Ni-B Coating
(2018-04-24)
Phase transformation behavior, micro structural development, mechanical and tribological properties of electroless Ni-B coating was characterized using different characterization techniques. As deposited electroless Ni-B ...
