PDE-based parameterization method in Isogeometric Analysis and its application in twin-screw rotary compressors

Rotary-type positive displacement machines (PDMs) are widely used in industry to produce high-pressure air and gases. A recent trend is screw compressors with variable pitch and/or variable rotor profiles, which enable such performance improvements. The core idea is to vary the pitch angle and/or the rotor profile from the inlet to the outlet either in discrete segments or continuously. The goal of this two-years project is to develop volumetric parametrization methods for twin-screw rotary compressors using Isogeometric Analysis.
