The GUI shows 3-D geometry of the ex-USS
Shadwell/688 test area and its subsystems
ventilation, firemain, etc.
3
closed doors
opened doors
and allows for controlling the state of the
junctions (doors, hatches) as well as fans and
dampers
4
Only deck 1 and sail shown here
selected parts of the ship can be examined,
zoomed-in, rotated
5
Only deck 3 and two compartment at deck 4
selected parts of the ship can be examined,
zoomed-in, rotated
6
the control room is of particular interest on
the left side controls for setting the
simulation parameters
7
the control room filled with smoke (10 gt
visibility gt 2)
8
Temperature is shown in color yellow only
protected men allowed (gt333K), red inhabitable
(gt400 K)
9
The control room, filled with smoke shown from
the other side also shown ventilation ducts
10
Visibility in the control room dropped below 2
11
Temperature and smoke shown simultaneously
12
Only temperature is shown
13
Comparison of two simulations with different
setting of the ventilation system
14
The same two simulations, only temperatures are
shown
15
The same two simulations, only smoke is shown
16
Comparison of two simulations, with and without
frame bays (154 s after the fire started)
17
The same two simulations (240 s after the fire
started)
18
The same two simulations (416 s after the fire
started)
19
The same two simulations (583 s after the fire
started)
20
The same two simulations (941 s after the fire
started)
21
The same two simulations (943 s after the fire
started) only temperature shown
22
The same two simulations (1064 s after the fire
started) oxygen depletion shown (redlt12)
23
The same two simulations (1198 s after the fire
started) only smoke shown
