TWO-DIMENSIONAL EXPERIMENTS ON THE EFFECT OF HULL FORM ON HYDRODYNAMIC IMPACT.
Abstract
An extensive experimental study was undertaken to evaluate the fundamental parameters affecting the two-dimensional water-entry problem. The effects of ship forebody form, impact velocity, and mass on the magnitudes and time histories of impact pressures were determined and results compared with theoretical predictions. It was found that the theory predicts pressure, force, and impulse that show reasonable agreement with experimental results for sections having fine form, i.e., those of relatively V-form with small flat bottom. However, there is increasing divergence between experimental results and theoretical predictions for relatively blunt forms with large flat bottoms. (Author)
