Wake waves of a planing boat: An experimental model

The wake waves generated by the steady movement of a planing hull are analyzed means towing tank tests. Two sets waves, including divergent and transverse identified then analyzed. wave period is seen to decrease increase in speed vessel. These damp temporally. mechanisms that lead damping were found depend on orbital Reynolds number semi-planing regime, though in-planing regime function boat. angle with Froude number, rate which becomes relatively large regime. Transverse captured through measurements, it shown while their longer than those they not noticeably damped. Throughout spectral analysis, demonstrated reach higher level nonlinearity and, hence, energy distributed over boarder range frequency. height observed become lower speed, but as increases, probability density curves surface elevation deviate more from Gaussian distribution.
