    • Compressed air energy savings on an iron production plant 

      Zeelie, Lourens Edwill (North-West University (South Africa) , Potchefstroom Campus, 2016)
      In the past several decades, energy efficiency has become increasingly important. A large driver behind this is reducing greenhouse gases that are caused by the combustion of fossil fuels. Most electricity generated in ...
    • The implementation of a dynamic air compressor selector system in mines 

      Van Niekerk, Mattheus Hendrikus Pieters (2015)
      The generation of compressed air comprises 20% of the total electricity usage in the mining industry, although compressed air is often seen as a free source of energy. There are however significant costs associated with ...
    • Modelling of losses in multi-stage axial compressors with subsonic conditions 

      Swift, William James (North-West University, 2003)
      The need was identified to develop an analytical performance prediction code for subsonic multistage axial compressors that can be included in network analysis software. It was found that performance calculations based ...
