TITLE : TACT : Cooling Tower Simulation

BY : CHAM Development Team - D Radosavljevic - S N Drake
FOR : TACT development programme
DATE : 1988
PHOENICS Version : PHOENICS 1.4 - TACT

DETAILS :

• Three-Dimensional steady flow
• Curvilinear(BFC) computational grid

NOTES :

• Simulation of a wet natural-draught cooling tower used in many steam power stations for cooling large quantities of water by direct contact with the athmosphere
• PHOENICS-TACT predicts the complex three-dimensional effects resulting from interaction between the cross-wind and the cooling tower flow field
• Simulation features :

      - Inlet water temperature    20 C       - Tower Height  115.4 m
      - Cooling range              12 C       - Base Radius    42.6 m
      - Block power               350 MW      - Exit Radius    24.0 m
  

Pictures are as follows : 1. Computational grid and Tower shell 2. Velocity vectors in symmetry plane 3. Air temperature contours in symmetry plane
