Abstract

This study aimed to highlight the mass flow and boost pressure performance of an electrically operated axial compressor. This compressor proposed and developed by its authors^[1] was mounted on a diesel engine, which is fitted to a VW Golf 4. A mathematical model was developed in MathCad for the overall calculation of this compressor, determining the boost pressure and the theoretical air flow. The mathematical model also highlights the increase in the boost in each stage of the compressor, but also the mechanical work consumed. The compressor was made of the following parts: fan 1 which is designed to take the air and to direct it axially into the second stage, where is the second fan with a smaller diameter and a number of higher revolutions, the control unit which allows the speed of each fan to be adjusted and the part to be protected against electrical shock. To determine the air flow, a diaphragm has been created which has been fixed by 6 screws at the compressor outlet, fitted with holes for measuring the difference in pressure. In this study, the pressure at several characteristic points of the compressor will be measured using an integrated differential sensor assembly. LabVIEW program was used to determine characteristic values according to the speed of the axial compressor and pressure variation can be seen on a laptop interface during compressor operation. After determining the mass flow, the turbocharging pressure can also be determined from the calculation.
