In this study an original analysis of the geometric design of a particular internal pump and an investigation on its theoretical performances are presented. The first part of the work is focused on the geometry of the machine, which is similar to the classical epitrochoidal pumps, but characterized by more complex rotor profiles. Suitable parameters are pointed out in order to completely define the geometry of the machine. In the second part of the paper proper indexes are set and evaluated as functions of the design parameters, in order to evaluate the performance of the machine. The analysis performed allows to highlight the main advantages and drawbacks of this original design in terms of operating performance in comparison with the classical trochoidal pumps.

Abstract
In this study an original analysis of the geometric design of a particular internal pump and an investigation on its theoretical performances are presented. The first part of the work is focused on the geometry of the machine, which is similar to the classical epitrochoidal pumps, but characterized by more complex rotor profiles. Suitable parameters are pointed out in order to completely define the geometry of the machine. In the second part of the paper proper indexes are set and evaluated as functions of the design parameters, in order to evaluate the performance of the machine. The analysis performed allows to highlight the main advantages and drawbacks of this original design in terms of operating performance in comparison with the classical trochoidal pumps.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
