WP8 – Screw Machines

The work package is devoted to the integration of the novel CAE technologies developed in WP2, WP3, WP4 into the design workflow for the MOTOR Product screw machines.

Objectives

  • To create parametric geometry models of twin-screw machines turbines using advanced geometric functionality from WP2 <link>
  • To create a multi-stage optimization tool for the design of twin-screw machines with variable rotor pitch
  • To demonstrate the overall advantages of variable rotor pitch screw machines in terms of energy efficiency for different applications

 

Description of work

  • Task 8.1: Analysis-suitable volumetric NURBS parameterization for twin screw machines generated from input data in the design space (profile cross sections, parametric function of rotor pitch along the z-axis, length-to-diameter ratio, inner-volume ratio, gap heights, inlet/outlet pipes
  • Task 8.2: Multi-stage shape optimization tool for twin screw machines combining 0D chamber-model simulations with detailed 3D CFD simulations for selected configurations to obtain improved gap flow coefficients for the 0D simulations
  • Task 8.3: Multi-stage shape optimization of twin screw machines with variable rotor pitch for different operating conditions
  • Task 8.4: Design and realization of a prototype twin screw machine with variable rotor pitch (dual-pitch rotor)
  • Task 8.5: Building test rig and experimental investigation of the prototype twin screw machine
