Table 4
Capture efficiency (CE) of the simulation cases and the percent increase (%) in CE by exhaust flow rate and window position.
| | Exhaust flow rate (m3/min) | Window height (m) | Window position | | Front | Side | Back |
| | CE (%) | | | | | | 6.72 | 1.2 | 81 (case A) | 33 (case B) | 56 (case C) | | 2.4 | 83 (case D) | 49 (case E) | 65 (case F) | | 12.16 | 1.2 | 97 (case G) | 85 (case H) | 97 (case I) | | 2.4 | 97 (case J) | 97 (case K) | 77 (case L) | | Percent increase in CE from low to high flow rate (%) | 1.2 | 20 | 158 | 73 | | 2.4 | 17 | 98 | 18 |
