EFFECT OF WAKE ON WAVE RESISTANCE OF A SHIP MODEL

For the purpose of resolving the question of the influence of its wake on the wavemaking resistance of a ship, the total, viscous and wavemaking resistance of a Series 60 ship model were measured with the wetted surface first smooth, and then rough. It was found that the wave resistance was significantly less with the rough surface, implying that viscous effects should not be neglected in the development of higher-order wave theory. Since the wake- survey method was used to determine the viscous resistance, the opportunity was taken to compare the results with roughness with the values obtained by calculating the boundary layer on the rough 'equivalent' body of revolution, with satisfactory agreement.
