Webinar 20: Grid generation for variable geometry screw machines using SCORG

Posted on April 22, 2021

In this webinar, Dr Sham Rane presents the application of the SCORG grid generator to model variable geometry twin screw machines.


  • SCORG Grid Generation
  • Variable Lead and Variable Profile rotors
  • Conical Internally geared rotors of Vert type


The webinar discusses some of the benefits of variable geometry twin-screw rotors compared to the traditional uniform rotors. Sealing line length, blow-hole area, and internal pressure rise due to built-in volume index are some of the parameters influenced by variable geometry rotors, impacting the compressor’s performance. In addition, an adaptable framework for deforming grid generation using SCORG and modelling with ANSYS CFX solver is presented. 


A case study on dry air twin-screw compressor with uniform, variable lead and variable profile rotors is showcased using the CFD model.
