Manufacturing a 9-Meter Thermoplastic Composite Wind Turbine Blade: Preprint
, 2017 Currently, wind turbine blades are manufactured from a combination of glass and/or carbon fiber composite materials with a thermoset resin such as epoxy, which requires energy-intensive and expensive heating processes to cure.

International Journal for Numerical Methods in Fluids, EarlyView.Compared to experimental data of thermophysical properties of NFs, semi‐empirical models cannot estimate FOM correctly. For all working fluids, applying a converging channel instead of the canonical case was inefficient. Diverging channel was always favored compared to the canonical case. For less effective NFs, both lowering the reference velocity and

Dynamic stall of an experimental wind turbine blade
, 2016 To understand the complex flow phenomena over wind turbine blades during stall development, a scaled three-dimensional non-rotating blade model is designed to be dynamically similar to a rotating full-scale NREL 5 MW wind turbine blade.

Macromolecular Materials and Engineering, EarlyView.Incorporating 0.3 wt.% COOH‐functionalized MWCNTs, well dispersed via ultrasonication, into epoxy significantly enhances tribological and mechanical performance, reducing wear by 82% and COF by 32%. During sliding, friction breaks down MWCNTs into graphitic fragments, which are slowly released, forming a protective tribofilm.

VIBRATIONS OF A GROUP OF TURBINE BLADES
Journal of Zosen Kiokai, 1932 The object of this investigation was to study mathematically the effect of the deck band on the natural frequency of turbine blades in a group which are mounted on the rim of a turbine wheel rotating with a constant speed.For the purpose of obtaining the result the method of combination of two kinds of frequencies, one of which is that for an elastic ...

Materials Genome Engineering Advances, EarlyView.During the corrosion of Hf6Ta2O17 by CMAS, stable corrosion products—CaTa2O6 and HfSiO4 form at the interface, which hinder further corrosion of Hf6Ta2O17 by CMAS. This mechanism successfully explains the excellent CMAS corrosion resistance of the Hf6Ta2O17 thermal barrier coating.
