An Experimental Study on the Wave-Cancelling Effects of Large Bulbous Bow on the Passenger Coaster
초록
The wave-cancelling effects of a large bulbous bow on the coastal passenger boat have been investigated in deep and shallow water. The following characteristics have been cleared through resistance tests with the model of the Korea standard type coastal passenger vessel(LWL=25.8m, B=5.5m, T=1.65m) equipped with large bulbous bows of various sizes. (1) Over the range of Froude Number 0.30, the wavemaking resistance coefficients decrease 30% or more. (2) The optimum location of bulb center is around 8% L from F.P. (3) On the 120 G.T. passenger coaster which has a speed corresponding to Froude Number 0.34, the most advantageous bulb is the one whose
