  • Preparation and characterisation of palladium composite membranes. 

    Keuler, Johan Nico (Stellenbosch : University of Stellenbosch, 1997-12)
    This study focuses on the preparation and characterization of palladium-silver-nickel composite membranes. Electroless plating was used to deposit thin metal films on aluminazirconia membrane supports. Palladium conversion, ...

  • A design programme for dilute phase pneumatic conveyors 

    Wodrich, Karsten H. K. (Stellenbosch : University of Stellenbosch, 1997-12)
    A computer programme for the simulation of dilute phase pneumatic conveying of solids is presented. This includes positive pressure and vacuum pneumatic conveying. The characteristic conveying parameters such as the ...

  • 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 ...

  • Characteristics of gas-liquid counterflow in inclined ducts with particular reference to reflux condensers 

    Zapke, Albert (Stellenbosch : Stellenbosch University, 1997-12)
    ENGLISH ABSTRACT: An experimental investigation on gas-liquid counterflow in inclined rectangular ducts is conducted. The pressure drop across the sharp-edged gas inlet and the pressure gradient inside the duct are ...
