(1) To address issues such as a low compression ratio and severe leakage in uniform wall thickness vortex compressors, this paper adopts a new scroll compressor model with a variable diameter double arc combined profile, which has a larger pressure ratio and smaller leakage than the scroll compressor with equal wall thickness that can bring new ideas and methods to the research in the field of scroll compressors. (2) This paper determines the theoretical equation of the variable diameter dual circular arc vortex profile and the combined profile, and infers mathematical models for the leakage line length, working chamber volume, and gas leakage per unit rotation angle of the vortex compressor, followed by simulation. (3) The results show that compared to the uniform wall thickness involute profile, the variable diameter dual circular arc combined profile model reduces the leakage line length by 25%, increases the average total pressure at the working chamber outlet by 2.38%, and decreases the leakage amount by 3.2%, consistent with theoretical analysis. (4) The tangential leakage caused by the radial gap in the variable diameter dual circular arc combined profile model has a significant impact on the uneven distribution of temperature and velocity fields in the working chamber of the vortex compressor, but a smaller impact on the pressure field.

The lubrication and dynamic behavior of the orbiting scroll (OS) is crucial to understanding and controlling the leakage between working chambers and the contact between scrolls in the compressor. In this study, a novel comprehensive model consisting of the OS, bearings, rotor, and frames is developed and validated by experiments. This paper demonstrates, for the first time through the tribo-dynamics analysis method, that the rotor dynamics have a significant impact on the flank gap size between scrolls via the interaction of the sliding bearings. The reduction of actual orbiting radii of OS is found to be caused by the bending and tilting of the rotor. However, though increased rotational speeds can narrow the flank gaps, the impact between scrolls should be addressed in these cases. The tribo-dynamic analysis illuminates the direction of the optimal design of compression components in the scroll compressor.
