Parametric Representation of Scroll Geometry with Variable Wall Thickness
, 2012 In a scroll-type compressor, compression is achieved by relative contact between two spiral curves. Since the scroll invention by Leon Creux in (1905) multiple methods have been developed for calculating the scroll geometry and pocket volume.

Implementation of scroll compressors into the Cordier diagram
IOP Conference Series: Materials Science and Engineering, 2019 Abstract Selecting the most suitable machine type for a specific compression task is an essential step to ensure a reliable and economical operation of the overall system. For this, the eligibility of a compression principle can be estimated by the enhanced Cordier diagram by Grabow based on only a few input parameters (specific ...
