Abstract

In previous papers the authors have analyzed the functioning of the three lobe supercharger. This analysis was made possible by a complete analytical model of the rotors. The dynamic transformation of the chambers occupied by the fluid allows us to point out specific problems regarding trapped volumes and to design special devices to avoid these problems. As a result it is possible to simulate the performance of the compressor and to propose an analytical model in order to determine the dynamic loads on the rotors. The topic of this paper is the comparison between the performances achieved by helical and spur rotors, with particular attention to the loads, force and moment, acting on the rotors.
