AN EXPERIMENTAL STUDY OF SHIP RESISTANCE AND MOTIONS IN WAVES -- A TEST FOR LINEAR SUPERPOSITION.

Abstract

A series of experiments were performed to check the linear superposition of resistance of component waves on a composite wave. A wave train, having only two components of uniform waves, was generated. The resistance in each of the wave components was measured and the linear superposition of this data compared with measurements in the composite wave. The results indicate that the linear superposition underestimates the resistance in the composite wave. The degree of underestimation depends upon the severity of the ship motions. With slamming and with green water on the deck, the predicted resistance, based on linear superposition, was considerably less than the actual measurement. For moderate waves and smooth motions the difference was smaller. (Author)
