Study on a new aerodynamic model of HAWT based on panel method and Reduced Order Model using Proper Orthogonal Decomposition

Wang, Q.; Wang, Z.X.; Song, J.J.; Xu, Y.; Xu, J.Z. - In: Renewable Energy 48 (2012) C, pp. 436-447

A new aerodynamic model, PANROM, of horizontal axis wind turbine (HAWT), which couples 3D Panel Method and Reduced Order Model (ROM) based on Proper Orthogonal Decomposition (POD), is presented in this paper. By integrating the characters of the two different numerical methods, the PANROM model...

Blade layers optimization of wind turbines using FAST and improved PSO Algorithm

Liao, C.C.; Zhao, X.L.; Xu, J.Z. - In: Renewable Energy 42 (2012) C, pp. 227-233

Based on the blade layers, a multi-criteria constrained optimum design model for wind turbine blades is developed and programmed. This model is pursued with respect to minimum blade mass to reduce the cost of wind turbine production. Because the spar caps are the main parts to endure the loads...

X-RAY EMISSION FROM THE METASTABLE COMPONENTS OF SLOW Ar16+ BEAM ON METALLIC SURFACES

ZHANG, H. Q.; CHEN, X. M.; LIU, Z. Y.; YANG, Z. H.; XU, … - In: Surface Review and Letters (SRL) 16 (2009) 03, pp. 463-467

K-shell X-ray emission was observed in the neutralization process of Ar16+ interacting with beryllium and molybdenum at slow speed (less than Bohr velocity). The K-shell X-ray emission came from the metastable component of Ar16+ beam with the configuration (1s2s) produced from electron cyclotron...
