A wind turbine blade profile analysis code based on the singularities method

Kamoun, Badreddine; Afungchui, David; Chauvin, Alain - In: Renewable Energy 30 (2005) 3, pp. 339-352

The aerodynamic characteristics of wind turbines are closely related to the geometry of their blade profiles. The innovation and the technological development of wind turbine blade profiles can be centred on two tendencies. The first is to improve the shape of the existing airfoils and the...

Combustion of peanut shells in a cone-shaped bubbling fluidized-bed combustor using alumina as the bed material

Arromdee, Porametr; Kuprianov, Vladimir I. - In: Applied Energy 97 (2012) C, pp. 470-482

This paper reports experimental studies on burning peanut shells in the conical fluidized-bed combustor using alumina sand as the fluidizing agent. Prior to combustion tests, hydrodynamic regimes and characteristics of a conical alumina–biomass bed were investigated under cold-state conditions...

Design of a horizontal axis tidal current turbine

Goundar, Jai N.; Ahmed, M. Rafiuddin - In: Applied Energy 111 (2013) C, pp. 161-174

Pacific Island Countries (PICs) have a huge renewable energy potential to meet their energy needs. Limited resources are available on land; however, large amount of ocean energy is available and can be exploited for power generation. PICs have more sea-area than land-area. Tidal current energy is...

Energy saving potential of night ventilation: Sensitivity to pressure coefficients for different European climates

Ramponi, Rubina; Angelotti, Adriana; Blocken, Bert - In: Applied Energy 123 (2014) C, pp. 185-195

The suitability of night ventilation to reduce the cooling demand in buildings can be evaluated by coupling Airflow Network Models to Building Energy Simulation tools. To estimate wind-induced ventilation, pressure coefficients (Cp) on the building envelope are key inputs, as well as local wind...

Performance prediction of NREL (National Renewable Energy Laboratory) Phase VI blade adopting blunt trailing edge airfoil

Lee, Sung Gun; Park, Sang Jun; Lee, Kyung Seo; Chung, … - In: Energy 47 (2012) 1, pp. 47-61

This study uses Computational Fluid Dynamics (CFD) to evaluate the performance of a blade with blunt airfoil which is adapted at the root. FLUENT software is used of numerical analysis, and ICEM-CFD is used for generating mesh representations. The experimental conditions of the blade used for...

Explanatory and prediction power of two macro models. An application to van-involved accidents in Spain

Dadashova, Bahar; Ramírez Arenas, Blanca; McWilliams … - In: Transport Policy 32 (2014) C, pp. 203-217

accidents: linear regression with Box–Cox transformed variables and autoregressive errors (DRAG), and an unobserved components … that the DRAG-type model yields slightly better predictions for all four models compared to UCM. With these macroeconomic …

Transport of particles in fluids

Herrmann, Hans J.; Andrade, José S.; Araújo, Ascânio D. - In: Physica A: Statistical Mechanics and its Applications 372 (2006) 2, pp. 374-386

The interaction of moving fluids with particles is still only understood phenomenologically when the Reynolds number is not vanishing. I will present three different numerical studies all using the solver “fluent” which elucidate this issue from different points of view. On one hand, I will...

An Anatomy of Fundamental Indexing

De Moor, Lieven; Fang, Liu; Sercu, Piet; Vinaimont, Tom - Faculteit Economie en Bedrijfswetenschappen, … - 2012

stocks overperform but are underweighted and vice versa, implying a `drag' which FI claims to avoid. Mixed into the debate is … necessary to avoid drag, but the cross-sectional patterns are also quite variable over time. In short, there are style shifts … and they are unstable. To estimate the benefits from drag avoidance, purged of style shifts without having to rely on …
