PHOENICS Version : PHOENICS 1.4 - TACT

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

- 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
