KELVIN WAKE MEASUREMENTS OBTAINED ON FIVE SURFACE SHIP MODELS

Radar and optical images recently taken of ship wakes at sea have stirred interest in obtaining model-scale Kelvin wake data. The distinctive Kelvin wave pattern consists of diverging and transverse waves. Experimental measurements of the Kelvin wake were obtained for five surface ship models representing an assortment of naval combatants, including a cruiser, an aircraft carrier, and three destroyers. Measurements were performed in the Carriage I basin at the David Taylor Research Center (DTRC) using capacitance wave probes, a newly developed laser-slope meter, and close-range photogrammetry techniques. All the models were tested without propulsion at a Froude number of 0.25. Similarities and differences in the wave patterns were documented and discussed. In addition, Kelvin wake data were obtained for other conditions such as speed variation and altered trim, with and without propulsion. The effect of these changes on the wave system is also discussed.
