• The design of a low-noise rotor-only axial flow fan series 

      Van der Spuy, Sybrand Johannes (Stellenbosch : University of Stellenbosch, 1997-12)
      ENGLISH ABSTRACT: A design routine was derived for designing a series of rotor-only axial flow fans. The routine was applied by designing two different series of axial flow fans. The first design was for a general application ...
    • Perimeter fan performance in forced draught air-cooled steam condensers 

      Van der Spuy, Sybrand Johannes (Stellenbosch : Stellenbosch University, 2011-12)
      ENGLISH ABSTRACT: Axial flow fan arrays form part of air-cooled steam condensers in direct drycooled power plants. This dissertation investigates the performance of axial flow fans when located at the perimeter of a fan ...
