WebAug 19, 2024 · Thin ship theory was also used to calculate drag components to determine the wave spectrum's fluctuation point by wave-cut in longitudinal and lateral directions. These methods make it easier to assume that the bulb is in the proper position. The comparison of drag coefficient components based on computation and experiments … WebIn particular, a well-known notable limitation of the thin-ship and slender-ship approxima-tions is that they yield wave-drag predictions that exhibit unrealistic overly large oscillations with respect to ship speed.
