Investigating Ship Wakes and Wave Patterns
Explore the visual similarities between ship wakes and Mach cones, considering various parameters such as boat velocity and length. Delve into wave equations, dispersion effects, and experimental results while addressing questions on water speed, wake formation, and wave models. Analyze the correlation between theory and experiment, emphasizing the importance of understanding water dispersion relations and the impact of different ship sizes and speeds on wave patterns.

Slidesgo School 6. Ship Wakes The wave pattern produced by a ship moving on the water is visuallysimilarto a Mach cone and depends on various parameters. Investigate the effect.
Theory Many wave equations and explanation of simple waves Mention Dispersion Wrong explanation of the effect Should not use Mach angle aproximation No Explanation of the effect of dispersion in ship wakes Mention a constant
Experiment Include different velocities of the boat Different lenghts of the boats No taking into account the length of the boats No explanation of the considered constant wavelengths
Results Claculated errror Fitted the experimental data with a model Correlation between theory and experiment Did not show the Kelvin-Mach transition of the wake Not all results are explained by the considered model
Questions for Discussion Do you think this speed of water is constant or does it depend on some kind of parameter? The envelope line of the Mach cone is created by the boundary of air and created vacuum, but the shape of the Ship wake is created by the boundary of water and water. Did you consider that, and do you think that can affect your theory? Sound waves are created by difference in pressure of air, however water is incompressible. So what is the main difference in the pattern of the wake from the Mach cone?
Questions for Discussion Are these the full formulas for water dispersion relations? Do you think that the gravity waves model holds of all sizes and speedsof ships?
