OpenFOAM case files for drag coefficient determination in automatic ball balancers

This repository includes

• A prototype of an OpenFOAM case file to calculate the drag at low Reynolds numbers on a sphere inside a section of an annular domain representing the geometry of an automatic ball balancer with a radial ball bearing contour on the raceway.
  • Prerequires:
    1. Linux OS or Windows Subsystem Linux (tested with Ubuntu)
    2. OpenFOAM (tested with OpenFOAM7 Version 20190708)
    3. python3
  • Usage
    1. create a copy of the OpenFoam case

       tar -xf OFcase.tar
       mv OFcase case001

    2. modify parameters.py inside the case folder

    3. execute

       cd case001
       chmod +x Allrun_parallel
       ./Allrun_parallel

• Results gained with this case file, which are presented in the associated publication.
