Generalized Circular and Elliptical Honeycomb Structures/Bundled Tubes : Effective Transverse Elastic Moduli
(2018-01-01)
Omnipresence of heterogeneity is conspicuous in all creations of nature. Heterogeneity manifests itself in many forms at different scales, both in time and space. Engineering domain being an exotic fusion of human creativity ...
Micro-Mechanisms Associated with Friction Stir Welding of Aluminum with Titanium
(2018-01-10)
Out of the known aerospace metal and alloys, Aluminium (Al) and Titanium (Ti) are important due to their unique combination of properties, such as strength, ductility and corrosion resistance etc. For these reasons, welding ...
Shock Wave-boundary Layer Interaction in Supersonic Flow over Compression Ramp and Forward-Facing Step
(2018-01-12)
Shock wave-boundary layer interactions (SWBLIs) have been studied ex-tensively due to their practical importance in the design of high speed ve-hicles. These interactions, especially the ones leading to shock induced ...
Experimental Study of Flow Past a Circular Cylinder with a Flexible Splitter Plate
(2018-01-04)
A circular cylinder is a geometrically simple bluff body that occurs in various practical applications. As with any bluff body, it exhibits large drag forces and a strong fluctuating lift force, both related to the strong ...
Nano Porous Alumina Based Composite Coating for Tribological Applications
(2018-02-06)
Anodisation is a surface treatment process, commonly used to form a protective oxide coating on the surface of metals like aluminium. Anodised coatings, being grown out of the base metal have excellent interface strength ...
Generation, Characterization and Control of Nanoscale Surface Roughness
(2018-01-11)
Surface roughness exists at many length scales-from atomic dimensions to meters. At sub-micron scale, the distribution of roughness is largely dependent on the process that generates the surface through the mechanisms of ...
A Design Concept of a Volumetric Solar Receiver for Supercritical CO2 Brayton Cycle
(2018-01-09)
Recently, the supercritical carbon dioxide (s-CO2) Brayton cycle has been identified as a promising candidate for solar-thermal energy conversion due to its potentially high thermal efficiency (50%, for turbine inlet ...
Continuum Modeling Of Adhesive Interaction Based On Interatomic Potentials
(2018-01-12)
Adhesion between solid bodies plays a prominent role in a wide variety of situations ranging from tribological applications to dust coagulation initiating the formation of planets. It can be due to various reasons like ...
Frequency-Tuning and Dynamic Simulation of Electrostatically Actuated Beams
(2018-01-03)
The resonance frequency of electrostatically actuated micromachined beams can be tuned substantially by applying a DC voltage bias, first by decreasing the frequency until the onset of pull-in and then by increasing it by ...
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 ...
