    Extraction performances of roof-mounted ventilators are compared using data from tests based on an Australian/New Zealand Standard. The results show that a single performance curve (embodying air extraction rates, wind ...
  • Coat Thickness in Wire-coating process with corrugated die 
    Huynh Ba (ASME - American Society of Mechanical Engineers, 2002)
  • Convective Cooling of an Extrudate 
    Huynh Ba (ASME - American Society of Mechanical Engineers, 2007)
    Convective heat transfer about an isothermal, cylindrical extrudate of constant diameter, issuing continuously from an extrusion die, is investigated numerically, using a commercial CFD software package. The hot extrudate ...
  • Cooling by free convection at high Rayleigh number of cylinders positioned above a plane 
    Huynh Ba (School of Engineering, The University of Queensland, 2007)
    Free convection cooling of isothermal circular cylinders positioned above a horizontal plane is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. Computation is performed ...
  • An experimental investigation of pressure loss in canvas fire hose 
    Doull Aaron; Huynh Ba (The University of Auckland, 2010)
    The NSW Rural Fire Service (RFS) of Australia uses canvas "lay flaf" fire hose to deliver water at an incident. A single "rule of thumb" figure for the estimated pressure loss over a length (approx 30m) of canvas hose is ...
  • Free Convection Cooling of a Horizontal Cylinder Positioned Above a Plane 
    Huynh Ba (Begell House Inc, 2006)
    Free convection about an isothermal circular cylinder positioned horizontally above a plane is investigated numerically, with the cylinder's surface temperature being higher than that of the surrounding fluid. Both ...
  • Free-Convection Flow Through a Two-Dimensional Box With Openings on Opposite Walls 
    Huynh Ba (South China University of Technology, Guangzhou, China, 2009)
    Free-convection flow through a two-dimensional rectangular box having openings at opposite corners on the vertical walls is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. ...
  • Heat Loss and Evaporation Rate from an Agitated Water Tank 
    Alonso Martin Hector; Revel Alex; Huynh Ba (AGH University of Science and Technology Press, 2009)
    ABSTRACT. Experiments have been performed to investigate the heat loss and evaporation rate from an open-top tank of heated water that is also agitated vigorously by air bubbling through it. High consumption of electrical ...
  • Influence of location, number and shape of corrugations in slider bearings 
    Loe Suminto; Huynh Ba (CSIRO Publishing, 2001)
    The effects of location and shape of a localised corrugation on the performance of a fixed inclined slider bearing are investigated numerically, using a finite element method. It is shown that normal force increases ...
  • Influence of temperature boundary conditions in the wire-coated process 
    Huynh Ba (Adelaide University, 2001)
    Influence of temperature boundary conditions on the flow field inside the die of the wire-coating process is investigated numerically, using viscous fluids of a Newtonian type for coating material and a finite element ...
  • Natural ventilation induced by solar chimneys 
    Huynh Ba (The University of Auckland, 2010)
    Natural-ventilation flow through a two-dimensional but realsized square room is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. The flow is induced by a solar chimney ...
  • Non-Isothermal Peristaltic Flow of Newtonian Fluids in a Circular Tube 
    Yun Min Su; Huynh Ba (ASME, 2009)
    Non-isothermal peristaltic flow of Newtonian fluids in a circular tube is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. Simulation is performed over a range of Reynolds-number ...

    Huynh Ba (Engineers Australia, 2008)
    Numerical investigation of the effects of thermal plumes rising from a heated horizontal plate positioned on the floor in a cross-flow is conducted, using a commercial Computational Fluid Dynamics (CFD) software package. ...
  • A numerical study of non-isothermal peristaltic flow of power-law fluids in a circular tube 
    Yun Min Su; Huynh Ba (ASME, 2010)
    Non-isothermal peristaltic flow of power-law fluids in a circular tube is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package that employs the Finite Volume Method. Simulation ...
  • Numerical study of slider bearings with limited corrugation 
    Huynh Ba (American Society of Mechanical Engineers, 2005)
    Influence of corrugation of limited extent on the performance of fixed-incline slider bearings of infinite width is investigated numerically. Effects of the corrugated section's parameters like its location, length, and ...
  • Performance of a new stator-diffuser design for an axial-flow pump unit 
    Czlonka Anna; Nelson Tony; Dibbs Richard; Huynh Ba (The University of Auckland, 2010)
    In an axial-flow pump unit with conventional stator and diftllser, often considerable energy is still present in the swirl (rotation) of the liquid leaving the stator. This energy will eventually be lost from the pump ...
