Abstract: The alternative mathematical model presented for the vortex dropshaft design is based on theoretical considerations and suitable experimental parameters. Such a model is different from the previous ones because it considers the possible existence of negative pressure at the dropshaft inlet. The hypothesis of negative pressure, obtained through experimental tests, allows to overcome some uncertainties of the previous models. The estimation of experimental parameters has been carried out by means of the elaboration of tests concerning a large number of working dropshafts. In the final part of the present paper two procedures for design and verification of vortex dropshaft have been shown.
