Investigations of the key mechanism of Carbon-Nanotube Actuators and their dependencies
, 2010 Future adaptable applications require electro-mechanical actuators with a high weight-related en-ergy. Among modern multi-functional materials carbon nanotubes (CNTs) have some special char-acteristics which give them the potential to solve this demand ...

An extended actuator cylinder model: Actuator‐in‐actuator cylinder (AC‐squared) model [PDF]
Wind Energy, 2019 AbstractIn this paper, the actuator‐in‐actuator cylinder (AC‐squared) model is presented. This model is an extension of the original actuator cylinder model of Madsen and is capable of modelling the effect of a two concentric actuation surfaces in 2D. The induced velocity at every point in the 2D field is affected by the force field acting on the two ...

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Advanced Engineering Materials, EarlyView.This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.
