Typically, a boundary layer starts out laminar and then transitions to turbulence at the critical Reynolds number. We can manipulate this process by using rough surfaces or small wires to 'trip' boundary layers into becoming turbulent earlier than they would naturally (golf ball dimples are a good example of this).
