... of other positions. This is probably due to the fact that the cylinder at C1-N is directly exposed to the upstream two-phase flow fluctuations. The drag periodic forces do not appear to increase with tube bundle depth beyond the first upstream tube. The very sharp peak at low frequency (around 2 Hz) in Fig...
