Experimental and numerical research of compressor performance parameters

Abstract

The development of hydraulic parts of a compressor is based on a simplified flow model (often one-dimensional), the methodology of which is externally supported by CFD simulations. The designed geometry is then verified on a scaled model using a different model gas than the working gas. The experiment on the model is able to provide a basis for assessing compliance with the required parameters and possibly for further optimization and refinement of the geometrical shapes of the hydraulic design. The experimental data and the calculated data are compared on the isentropic workflow and isentropic efficiency as a function of the volumetric flow rate at the machine intake.
