Journal ArticleDOI

Wind energy: Trends and enabling technologies

TL;DR: In this paper, the authors provide an exposure to the necessity for deployment of renewable energy sources and the worldwide installed capacity of wind power as well as a review of various wind technologies in conjunction with their applications and devices of operation.
Journal ArticleDOI

Intraglottal pressure profiles for a symmetric and oblique glottis with a divergence angle of 10 degrees.

TL;DR: Intaglottal pressure profiles for a Plexiglas model of the larynx with a glottis having a 10-degree divergence angle and either a symmetric orientation or an oblique angle are reported to suggest aerodynamic asymmetries could be a factor contributing to normal jitter values and differences in vocal fold phasing.
Journal ArticleDOI

Experimental study of combustion characteristics of nanoscale metal and metal oxide additives in biofuel (ethanol)

TL;DR: The results indicate that the amount of heat released from ethanol combustion increases almost linearly with n-Al concentration, and the combustion model that utilized Chemical Equilibrium with Applications was shown to be in good agreement with the experimental results.
Journal ArticleDOI

Flow visualization and pressure distributions in a model of the glottis with a symmetric and oblique divergent angle of 10 degrees.

TL;DR: The results suggest that theglottal obliquity studied here creates significantly different driving forces on the two sides of the glottis (especially at the entrance to the glOTTis), and that the skewed glottal jet characteristics need to be taken into consideration for modeling and aeroacoustic purposes.
Journal ArticleDOI

Intraglottal pressure distributions for a symmetric and oblique glottis with a uniform duct (L)

TL;DR: A Plexiglas model of the larynx, having a uniform duct shape and minimal diameter of 0.04 cm, was used to obtain wall pressure distributions resulting from internal airflow, indicating that the pressure distributions on the two sides of the glottis were essentially equal for the symmetric uniform case.
