1. A vortex generator comprising a first fin and a second fin, said first fin being arranged upstream of said second fin, wherein a shortest distance between a trailing edge of the first fin and a leading edge of the second fin is less than 50% of a length of the first fin, in that said first fin and said second fin are arranged such that the first fin affects a flow of air passing the first fin such that it is directed towards the second fin, in that the first fin has a non-zero camber, in that a cross section of a pressure surface of the first fin comprises a concave portion and in that said concave portion is arranged such that airflow passing over the first fin is directed towards a suction surface of the second fin.
