CASE B, light-stall case, mean angle of attack 11o

 
  
 Reynolds number  1.95*106
 Mach number  0.29
 mean angle of attack  11o
 pitching angle                        4.2osin(wt)
 reduced frequency   (k=0.5wLref/Uref)  0.1
  
The below given results display the amount of predictive accuracy obtained from different linear Boussinesq-viscosity models (SA & SALSA: one-equation models;   Wilcox & LLR: two-equation k-w models) for these type of flows.
