A New Miniature Wind Turbine for Wind Tunnel Experiments. Part I: Design and Performance

Miniature wind turbines, employed in wind tunnel experiments to study the interaction of turbines with turbulent boundary layers, usually suffer from poor performance with respect to their large-scale counterparts in the field. Moreover, although wakes of ...

Mechanical impact of dynamic phenomena in Francis turbines at off design conditions

François Avellan, Arthur Tristan Favrel

At partial load and overload conditions, Francis turbines are subjected to hydraulic instabilities that can potentially result in high dynamic solicitations of the turbine components and significantly reduce their lifetime. This study presents both experim ...

Wind farm density and harvested power in very large wind farms: A low-order model

Varun Sharma, Marc Calaf Bracons

In this work we create new understanding of wind turbine wakes recovery process as a function of wind farm density using large-eddy simulations of an atmospheric boundary layer diurnal cycle. Simulations are forced with a constant geostrophic wind and a ti ...

Active aerodynamic drag reduction on morphable cylinders

Pedro Miguel Nunes Pereira de Almeida Reis, Mark Andrew Guttag

We study a mechanism for active aerodynamic drag reduction on morphable grooved cylinders, whose topography can be modified pneumatically. Our design is inspired by the morphology of the Saguaro cactus (Carnegiea gigantea), which possesses an array of axia ...

Comprehensive power loss modelling to improve the performance of an Energy Recovery Station for water utility networks

François Avellan, Cécile Münch-Alligné, Loïc Andolfatto, Daniel Biner

The work presented in this paper details the methodology applied to inventory and estimate the power losses in a micro-turbine with counter-rotating runners. The separation between the impact of design parameters and operational parameters on each identifi ...

Electrical hubs: An effective way to integrate non-dispatchable renewable energy sources with minimum impact to the grid

Jean-Louis Scartezzini, Dasaraden Mauree, Amarasinghage Tharindu Dasun Perera, Vahid Moussavi Nik

A paradigm change in energy system design tools, energy market, and energy policy is required to attain the target levels in renewable energy integration and in minimizing pollutant emissions in power generation. Integrating non-dispatchable renewable ener ...

Bioinspired morphing wings for extended flight envelope and roll control of small drones

Dario Floreano, Stefano Mintchev, Flavio Noca, Grégoire Hilaire Marie Heitz, Matteo Di Luca

Small-winged drones can face highly varied aerodynamic requirements, such as high manoeuvrability for flight among obstacles and high wind resistance for constant ground speed against strong headwinds that cannot all be optimally addressed by a single aero ...
