... Both towing tank experiments and wedge drop experiments are used to experimentally study slamming events on planning craft. The work presented in this paper shows a unique comparison between these two experiments. The first experiment was a towing tank test of a rigid hull in waves conducted...

... water. Although this approach is based on original Zarnick 2D+t model, the hydrodynamic force is estimated using experimental wedge drop experiments in conjunction with the Logvinovich wedge water entry model. The analysis is repeated employing Savitsky prediction method and results are compared...

... in previously conducted experimental studies and uncertainties in numerical simulations, a combined study to fully understand the three-dimensional uid-dynamics e ects on the bottom of a wedge is presented herein. The focus of this paper is on a comparison of experiments and simulations on the water-entry...

... threshold, it is considered that the validation has not been still conducted enough. In this research, the free-running model experiments are conducted up to higher speed region i.e. Froude number of 0.7 or over, and the surf-riding region bounded by two thresholds ware experimentally obtained...

... to as the predictable zone. An analogous reasoning can be held for the negative x-direction. Experimental setup The experiments were carried out in the No. 1 towing tank of the Ship Hydromechanics Laboratory of the Delft University of Technology. The dimensions of this towing tank are: 142 m length, 4.22 m width...

... a standard Lagrangian FE approximation. Validation of the numerical method against experimental test data and closed form analytical solutions shows that the ALE-FE/FE continuum approach captures the impact behavior accurately. A detailed sensitivity analysis is conducted to study the role of air...

... to the measured force. Even though no information about the experimental procedure of data analysis was reported by Parkin (1956), results in figure 13 are in accordance with experiments with a maximum error of 7.6% at V = 0.155, while in the remaining cavitation index range the error is below 5%. The standard...

... available experimental data. Based upon this, the chosen commercial tool is thus-far found adequate for numerically exploring skirt finger drag using an explicit CEL approach. A preliminary finger model has been proposed based upon the exact geometry tested in prior large scale experiments. ACKNOWLEDGEMENTS...
