FOR : Demonstration case

PHOENICS version: HOTBOX-2022

DETAILS :

This case represents a real-life telephone exchange unit. The model is set up of 80 plates (electronic exchnage units), 1 solid (power supplu unit), 2 apertures and one internal fan. Turbulence model used LVEL. Electronic units generate heat and simulation is carried out to locate the hot spots.

Pictures are as follows :
