Calculation elements for establishing the design of a rotating machine that transports fluids

Abstract

The paper presents the operating principle and the constructive solution of a rotating machine with two profiled rotors. The calculation relations between the rotor radius and the height of the rotating piston are established, fundamental relations for the design of the rotating machine. The calculation results on the basis of a computation program are presented, results which specify by the coordinates (xi, yi) the contour of the rotor profile. At the end of the paper, the formula for calculating the flow rate transported by the machine and its driving power is analysed.
