Vortex generators are fitted to
- move transition point rearwards.
- move the transition point forwards.
- delay the onset of boundary layer separation.
Explanation
Vortex generators are small vanes that create vortices mixing high-energy free-stream air into the boundary layer. This re-energised, more turbulent boundary layer resists the adverse pressure gradient longer, delaying separation and improving control effectiveness at high angles of attack.
sasna asking:
transition point forward with the help of vortex gen. how it helps.......... confuses me??????

Rearwards, sure.
