Irregular Wave Transformation in a Boussinesq Wave Model

open access: yesCoastal Engineering 1986, 1986
Numerical wave models for shallow water waves are of particular importance for the calculation of the wave climate in harbours and coastal areas. Especially nonlinear time domain models, which are based on the Boussinesq-Wave- Equations, may be helpful in the future for simulating the interaction of currents with refraction, diffraction, reflection and

Prediction of resistance and propulsion performances using calm-water and resistance tests in regular head waves of a 1,800 TEU container ship

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2022
This paper predicts resistance and propulsion performances in regular and irregular head waves of a 1800 TEU container ship. ‘Calm-water tests’ and ‘resistance test in regular waves’ have been performed. Methods applied are the LVM-W and the revised ITTC-

Irregular Wave Overtopping of Seawalls [PDF]

open access: yesOCEANS '86, 1986
This paper discusses recent laboratory tests of irregular wave overtopping of coastal structures being conducted at the Coastal Engineering Research Center (CERC). Current model tests of seawalls has led to an improved method for predicting wave overtopping rates.

Towards active microfluidics: Interface turbulence in thin liquid films with floating molecular machines [PDF]

open access: yes, 2008
Thin liquid films with floating active protein machines are considered. Cyclic mechanical motions within the machines, representing microscopic swimmers, lead to molecular propulsion forces applied to the air-liquid interface. We show that, when the rate

Experimental Investigation of Wave-Induced Hydroelastic Vibrations of Trimaran in Oblique Irregular Waves

open access: yesShock and Vibration, 2016
The irregular wave condition, especially the oblique irregular wave condition, is the actual circumstances when trimaran is sailing in sea. In order to identify the characteristic of the wave-induced hydroelastic vibration in irregular waves, as well as ...

Expected Discharge of Irregular Wave Overtopping

open access: yesCoastal Engineering 1968, 1968
An experiment was carried out on the overtopping of mechanically generated irregular waves over vertical walls. The experimental discharge was almost in agreement with the expected discharge which had been calculated with the wave height histogram and the data of regular wave overtopping based on the principle of linear summation.

Irregular Wave Overtopping Rates

open access: yesCoastal Engineering 1984, 1984
Methods for estimating wave overtopping of coastal structures are reviewed and compared with the very limited available data and with each other. The different methods yield results which can vary more than an order-of-magnitude. For vertical seawalls, the U. S.
