Web30 de mai. de 2013 · Physicists rethink celebrated Kelvin wake pattern for ships. 30 May 2013. Accurate angles. Lord Kelvin may have been an accomplished sailor, but he might have missed a trick when he famously described the phenomenon of wakes fanning out at a constant angle of 19.47°, no matter the speed of the vessel. That is the claim of … WebWilliam Thomson (the famous physicist Lord Kelvin) found already in 1887 the remarkable fact that the angle at which the wake fans out is always the same, regardless whether the wake is caused by a duck, a boat, or a ship, as long as the water is deep as compared with the lengths of the generated waves [1].
