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 ...
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 ...
