overpridiction of reattachment point
 
Dear All, I solved backward facing step of kim et al geometry.1:3 step hight to whole diameter and 28*step hight whole length and 4*step hight inlet of step using k-eps (wall function) by a collocated simplec code. the reattachment point is around 9.4 .i don't know the reason of this overestimation instead of underpridiction.i prescribed k & eps at inlet but used uniform velocity inlet. at Re=69610.

Looking forward to hearing from you
