Abstract
This project deals with the 3D design of an impeller and an external volute for a centrifugal compressor through the combination of 2 compatible methodologies. To achieve a successful design, thermodynamic and geometric parameters were computed. Besides, a CFD analysis was carried out to determine the performance curves, which show that the calculations precisely represent the reality because the relative error between the calculation and the simulations output parameter was 3.26% for the efficiency, 3.31% for the outlet temperature, 13% for the total pressure outlet and 7.14% for the outlet static pressure. A validation of the simulation methodology was carried out by replicating the results of the investigation presented by Mojaddam, obtaining an error percentage of 11.69% for the total pressure ratio and a 3.89% of error for the isentropic efficiency.
