摘要: In this study, the effect of parameters playing a role in root flow behavior HAWT are only partly understood. To better reveal properties, study presents progression blade at two different geometries and tip speed ratios. The effects geometry ratio on evolution features investigated. This aims to answer following questions: (i) What behavior? (ii) How wake vortex affected by change these parameters? analysis velocity fields shows that radial changes with but remarkable difference is not observed ratio. formation three test cases because loading blades encountered. From circulation distribution along blades, while strong can be Blade 1, bound vorticity 2 builds up gradually when moving outboard, do show trace vortex.
