摘要：

This paper presents RANS simulations of the low-Reynolds-number flow past an SD7003 airfoil at Re = 6 x 10(4), where transition takes place across a laminar separation bubble. The transition prediction procedure using an approximate envelope method as well as a linear stability solver is discussed. The numerical results are validated against PIV- and force measurements obtained in several wind- and watertunnels and are also compared to XFOIL results. Good agreement is found within the operational range of the airfoil. (C) 2006 Elsevier SAS. All rights reserved.
