FOR : Demonstration case

PHOENICS version: HOTBOX-2022

DETAILS :

This case represents a real-life electronic system rack. The model is composed of the number of fully blocked and porous plates, solid elements, 5 apertures and fan; fan is a part of the equipment within the rack. Turbulence model used is LVEL model. System components generate heat and the simulation is used to find the maximum temperature.

Pictures are as follows :
