anyone had any luck hunting down a di gital version of the pöpel report?
(Pöpel, Franz Rapport Berich über die Voruntersuchnungen mit Wendelrohren mit verschniedener Wandform International Report, Institut für Gesundheitstechnik, Institute of Technology in Stuttgart, 1952. surely any university dealing with vortical flow mechanics (or self-organizing flow technology) could benefit from replicating and proving/disproving this phenomenon.
