Select a Design

Conventional Design

· Full-height, around-the-end serpentine baffles
· Baffling factor θ10 = 0.546 — Average
· Morrill Index: 2.61
· Spring flow condition, Q = 120,000 m³/day

CODECWATER Design

· Slot-Baffle Design — 3 vertical slots per baffle
· Baffling factor θ10 = 0.655 — Good
· Morrill Index: 1.99 ≈ 2.0 (ideal)
· Dispersion index σ reduced by 46%

Key takeaways:
· Baffling factor θ10 improves from Average → Good (+20%)
· Morrill Index drops from 2.61 to 1.99, approaching the ideal value of 2.0
· Dispersion index σ reduced by 46%, indicating significantly more uniform flow
· Spring flow condition, Q = 120,000 m³/day
