– Difference between steady fire and unsteady fire (academy reference should be mentioned.) and in my knowledge that steady fire is suit for fuel-controlled fire and unsteady fire is suit for sprinkler controlled.
– Discuss which type of fire is suitable for atrium, unsteady fire may not suitable for the courtyard of atrium, because the sprinklers is not well-function due to high ceiling height, but other than the courtyard of atrium, like shop area, the unsteady fire is also suitable for them.
– Continue the previous, discuss what will be the fire load at the courtyard of atrium, the function of courtyard of atrium, like the Chrisman will have the Christmas tree and it have a very high fire load, and sometime people may use the courtyard of atrium for hawker shop.
Assumed that the maximum heat release rate of Christmas tree is 3.5MW (reference should made, the actual number in my knowledge may wrong)
– Discuss different location will affect the total smoke generating rate,
balcony spill plume and axisymmetric fire plume (corresponding formula should included)
– Discuss the different fire rate and smoke generating rate in two different type of fire.
– Mention that the axisymmetric fire plume will occur in the courtyard of atrium and balcony spill plume will occur at the shopping area.
