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 ... -
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 ... -
Effect of Convection and Shrinkage on Solidification and Microstructure Formation
(2017-11-24)Understanding the fundamental mechanisms of solidification and the relative significance of different parameters governing these mechanisms is of vital importance for controlling the evolution of microstructure during ... -
Flow and Windage Heating in Labyrinth Seals
(2017-11-24)The ability to quantify leakage flow and windage heating for labyrinth seals with honeycomb lands is critical in understanding gas turbine engine system performance and predicting its component lifes. Variety of labyrinth ... -
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 ... -
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 ... -
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 ... -
Non-Dimensional Kinetoelastic Maps for Nonlinear Behavior of Compliant Suspensions
(2018-02-18)Compliant suspensions are often used in micromechanical devices and precision mechanisms as substitutes for kinematic joints. While their small-displacement behavior is easily captured in simple formulae, large-displacement ... -
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 ... -
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 ...
