A study of surface modifications of carbon nanotubes on the properties of polyamide 66/multiwalled carbon nanotube composites
(2013-10-29)
The effects of surface modification of carbon nanotube on the properties of polyamide 66/multiwalled carbon nanotube composites have been investigated. Polyamide 66 (PA66) and multiwalled carbon nanotubes (MWCNTs) composites ...
Computational Study of a Small Scale Vertical Axis Wind Turbine (VAWT) : Comparative Performance of Various Turbulence Models
(2013-09)
The paper presents a numerical approach to study of fluid flow characteristics and to predict performance of wind turbines. The numerical model is based on Finite-volume method (FVM) discretization of unsteady Reynolds-averaged ...
Aeroelastic vibration control of hybrid airships using Regenerative Actuators
(2013-07)
In this paper, an experiment is performed to investigate aeroelastic vibration control of a wing using regenerative piezoelectric actuators. Instead of the wing a plate with one pair of the piezoelectric actuator is used ...
Self-Powered Dynamic Systems
(2013-07)
This article concerns the concept of energy harvesting associated with dynamic systems. The particular area of work is the concept of fully or partially self-powered dynamic systems requiring zero or reduced external energy ...
Numerical simulation of combined mixing and separating flow in channel filled with porous media
(2013-05)
Various flow bifurcations are investigated for two dimensional combined mixing and separating geometry. These consist of two reversed channel flows interacting through a gap in the common separating wall filled with porous ...
A Study of Tribological Properties of Water-Based Ceria Nanofluids
(2013-03-01)
This paper presents an investigation on the potential tribological properties of the water-based cerium dioxide nanofluids. The nanofluids with different nanoparticle concentrations were prepared in a materials laboratory. ...
Delamination threshold load of composite laminate under low-velocity impact
(2013)
A key factor affecting the use of carbon fibre reinforced composite laminates is the low velocity impact damage which may be introduced accidentally during manufacture, operation or maintenance of the component. Among the ...
On Power and Control Systems of the Multibody Advanced Airship for Transport
(2013)
The concept of the Multibody Advanced Airship for Transport (MAAT) is presented. The power, propulsion and control systems of the airship are discussed. The energy required for operation of this airship is supplied by a ...
