Investigation on Transonic Characteristics of Turbine Cascades.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1998 Transosic characteristics of three similar turbine cascades (designed for same condition, but with slightly different curvature of blade suction surface after throat) were tested by high-speed cascade wind tunnel. Experimental data showed small difference of curvature of blade suction surface after throat affected loss coefficient in transonic region ...

Numerical analysis of transonic flow over the FFA-W3-211 wind turbine tip airfoil [PDF]
Wind Energy ScienceModern wind turbines are the largest rotating machines ever built, with blade lengths exceeding 100 m. Previous studies demonstrated how the flow around the tip airfoils of such large machines reaches local flow Mach numbers (Ma), at which the ...
