This case was carried out to demonstrate PHOENICS abilities for
CFD problem applied to HVAC and thermal comfort.
Geometry:
The lecture theatre modelled consists of series of seats row, a projection room at the back and a stage at the front. Its dimensions are: 18 metres by 16 metres by 6 metres high. Up to 275 persons can be seated in this lecture theatre.
Geometry (inside of the room).
Simulation:
There are five supply air diffusers visible on the first picture of the geometry, distributed as follows: two at the back of the room, one at the front, and one on each side. Each diffuser is injecting 550l/s at a temperature of 19 degrees C. The air is extracted through a shadow gap around the ceiling perimeter.
The wall temperature are set to 22 degrees C, the floor is at 21 degrees C and the ceiling at 24 degrees C. Each person is releasing a heat of 80 Watts to the room.
