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 ...
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 ...
Growth And Characterization of ZnO Nanostructures for Device Applications : Field Emission, Memristor And Gas Sensors
(2017-11-09)
Zinc oxide (ZnO) is perhaps one of the most widely studied material in the last two decades. It has received so much of attention because of its incredible potential for wide ranging applications. ZnO is a wide band gap ...
Laser-based Diagnostics and Numerical Simulations of Syngas Combustion in a Trapped Vortex Combustor
(2017-11-16)
Syngas consisting mainly of a mixture of carbon monoxide, hydrogen and other diluents, is an important fuel for power generation applications since it can be obtained from both biomass and coal gasification. Clean coal ...
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 ...
Stall Flutter of a Cascade of Blades at Low Reynolds Number
(2017-12-05)
Due to the requirements for high blade loading, modern turbo‐machine blades operate very close to the stall regime. This can lead to flow separation with periodic shedding of vortices, which could lead to self induced ...
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 ...
Power Loss Minimization for Drag Reduction and Self-Propulsion using Surface Mass Transpiration
(2017-11-29)
The remarkable efficacy with which normal surface mass transpiration (blowing and suction) alters a given base flow to achieve a desired predefined objective has motivated several investigations on drag reduction, ...
Viscous Vortex Method Simulations of Stall Flutter of an Isolated Airfoil at Low Reynolds Numbers
(2017-11-27)
The flow field and forces on an isolated oscillating NACA 0012 airfoil in a uniform flow is studied using viscous vortex particle method. The simulations are carried out at very low chord (c) based ...
