  • A review of commercial numerical modelling approaches for axial hydrokinetic turbine wake analysis in channel flow 
    Niebuhr, Chantel Monica; Schmidt, S.; Van Dijk, Marco; Smith, Lelanie; Neary, Vincent S. (Elsevier, 2022-04)
    Computational fluid dynamics is employed for detailed prediction of the hydrokinetic turbine performance and wake modelling. Of these, Reynolds-averaged Navier-Stokes (RANS) models are most widely used due to their ability ...
  • A review of low head hydropower technologies and applications in a South African context 
    Loots, Ione; Van Dijk, Marco; Barta, Bo; Van Vuuren, S.J.; Bhagwan, Jay (Elsevier, 2015-10)
    This paper provides a review of available low head hydropower technologies, followed by the identification of sites where the technologies can be implemented, applied specifically to a South African context. The potential ...
  • Small-scale hydropower development for rural electrification in South Africa 
    Van Dijk, Marco; Van Vuuren, Fanie; Bhagwan, Jay; Loots, Ione (South African Institution of Civil Engineering, 2014-06)
    Although the electrification of urban areas and some informal settlements in South Africa has been achieved during recent years, many rural areas still require intervention to provide a reliable and sustainable electricity ...
  • Tapping untapped renewable energy 
    Van Dijk, Marco; Van Vuuren, Fanie; Bhagwan, Jay; Kurtz, Adriaan (South African Institution of Civil Engineering, 2012-06)
    In water distribution networks in South Africa, water is often fed under gravity from a higher reservoir to another reservoir at a lower level. The high pressure head at the receiving reservoir is then dissipated through ...
  • Water infrastructure asset management addressing the SDGs through energy recovery 
    Bonthuys, Gideon Johannes; Blom, Petrus; Van Dijk, Marco (South African Institution of Civil Engineering, 2018-06)
    Energy recovery through conduit hydropower has the potential to help lessen the impact of both the energy and water crises in South Africa. Energy recovery and leakage reduction also have the potential to increase the ...
