ABSTRACT Improvements in the aerodynamic design will lead to more efficiency of wind turbines and higher power production. In the present study, a 3D parametric gas turbine blade geometry building code, 3DBGB, has been modified in order to include wind turbine design capabilities. This approach enables greater flexibility of the design along with the ability to design more complex geometries with relative ease. The NREL NASA Phase VI wind turbine was considered as a test cas...

ABSTRACT Considerable reserves of oil sands are located in northernAlberta. Exploitation of these reserves has been instrumental in the development of theAlbertaeconomy. Mining and processing techniques, including “ in situ ” processing and surface mining/aqueous treatment, are presented. Oil assisted flotation and solvent extraction are discussed as possible future processing altern...
