Numerical investigations of passive flow control elements for vertical axis wind turbine
In this paper we numerically investigate the possibilities to control the dynamic stall phenomenon, with application to vertical axis wind turbines. The dynamic stall appears at low tip speed ratio (TSR

The dynamic stall appears at low tip speed ratio (TSR<4) and it has a great impact on structural integrity of the wind turbine and power performances. For this reason we performed a CFD 2D analysis of the dynamic stall phenomenon around NACA 0012 airfoil equipped with a passive flow control device, in pitching motion at relative low Reynolds number (∼105). Three passive flow control devices are numerically investigated: a turbulence promoter mounted on the leading edge, a thin channel and a step on the upper surface of the airfoil. For the present studies, the unsteady Reynolds averaged Navier-Stokes (RANS) model is the suitable approach to perform the dynamic stall simulations with an acceptable computational cost and reasonable accuracy. The results are compared to those of an existing experimental case test for unmodified NACA 0012 airfoil. The capability of this device was investigated numerically on a vertical axis wind turbine (2D model), where blades are generated with NACA 0018 airfoil.</description><identifier>ISSN: 0094-243X</identifier><identifier>EISSN: 1551-7616</identifier><identifier>DOI: 10.1063/1.4904596</identifier><language>eng</language><publisher>Melville: American Institute of Physics</publisher><subject>Aerodynamics ; Computational fluid dynamics ; Computer simulation ; Flow control ; Fluid flow ; Investigations ; Mathematical models ; Pitching motion ; Reynolds averaged Navier-Stokes method ; Reynolds number ; Stalling ; Structural integrity ; Tip speed ; Two dimensional analysis ; Two dimensional models ; Vertical axis wind turbines ; Wind turbines</subject><ispartof>AIP Conference Proceedings, 2014, Vol.1637 (1), p.340</ispartof><rights>2014 AIP Publishing LLC.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>309,310,780,784,789,790,23930,23931,25140,27925</link.rule.ids></links><search><creatorcontrib>Frunzulica Florin</creatorcontrib><creatorcontrib>Dumitrache Alexandru</creatorcontrib><creatorcontrib>Suatean Bogdan</creatorcontrib><title>Numerical investigations of passive flow control elements for vertical axis wind turbine</title><title>AIP Conference Proceedings</title><description>In this paper we numerically investigate the possibilities to control the dynamic stall phenomenon, with application to vertical axis wind turbines.
