Abstract: Centrifugal compressors are widely used across industries like oil and gas, chemicals, energy generation, and HVAC systems. They convert gas kinetic energy into high-pressure energy. The impeller and diffuser play key roles in this process. Designing the impellers 1D Meridional plane is critical for sizing and operational characteristics. This study establishes an analytical design methodology to determine impeller parameters, satisfying the pressure ratio, efficiency, and mass flow rate requirements. Further, Blade parameters to withstand operational stresses are also determined. Computational fluid dynamics (CFD) validates the model using the SST k-ꞷ model, ensuring reliable results through mesh convergence. The simulation aligns well with analytical parameters. This study provides a strong foundation for optimising analytical compressor design methodologies.

Keywords: centrifugal compressor; impeller; preliminary design; meridional plane.
