This master's thesis addresses the challenge of accurately modeling the operation of scroll compressors, where the scroll geometry significantly affects efficiency and leakage. We developed a numerical model for scroll generation and contact point detection using the nearest-point search method. A hybrid approach was applied, combining an analytical compression model with CFD simulations and experimental measurements. We estimated mass flow due to leakage and analyzed the impact of rotational speed on isentropic efficiency. Results show that the numerical approach enables time-dependent calculation of
suction volume, accurate contact detection, and increased efficiency with higher rotational speeds.
