Wave Resistance - Coggle Diagram
Wave Resistance
Speed-length ratio
Higher between 1,5 and 3
Froude Nbr
Wave generators
Bow
Stern
Reinforced wave
Stern wave crest
at the Bow wave crest
Interferência construtiva
Wave reinforcement or cancelation depends on relation \( l/L \)
\( l/L \) approx 1 or even
reinforced
\( \frac{l} {L}=\frac{V^2} {L} \)
\( \frac{V} {\sqrt{L}} \)
Speed-length ratio
Create wave
spends energy
Proportional to
Breadth of wave
Square of the wave`s height
Diminished wave
Stern wave crest
at the Bow wave trough
Wave length
\( l=0.557V^2 \)
V - wave velocity (same as ship)
Wave generator
separated by shiplength L
