An investigation of numerical analysis for modeling free-surface elevation from flow over a shallowly submerged 2D naca0012 hydrofoil

The bulbous bow is a common feature for large displacement vessels. The purpose of the bulbous bow is to reduce the bow wave, hereby making use of wave cancellation theory. The main drawback of these type of bows is that the drag reduction effect is only present for a limited range of sailing speeds. If the transit velocity is altered, the...

Sediment transport in case of irregular non-breaking waves with a current

Investigation to sediment transport rate in case of waves and currents, tests executed in the wave-current flume of the laboratory of Fluid mechanics of TU Delft. Sediment transport was measured using sand of 100 micron; comparison to similar tests with 200 micron sand.

Sediment transport concentrations and sediment transport in case of irregular non-breaking waves with a current

In many coastal, engineering problems the sediment transport plays a part. A transport gradient causes accretion or erosion. Various models, such as that of Bijker, Engelund and Hansen (van de Graaff and van Overeem, 1979) and Nielsen (1985) are available to estimate the sediment transport rate if the hydraulic and environmental conditions (wave...
