Theory of weakly damped free-surface flows: a new formulation based on potential flow solutions

, 2007
Several theories for weakly damped free-surface flows have been formulated. In this paper we use the linear approximation to the Navier-Stokes equations to derive a new set of equations for potential flow which include dissipation due to viscosity.

Are waves all localized in two dimensional random media?

, 2002
It has been the dominant view for over two decades that all waves are localized in two dimensions for any given amount of disorder. Here, I would like to raise questions about this assertion. The discussion leads to the conclusion that there is a lack of

Bow design for low added resistance in waves

, 2023
Med tanke på å redusere utslipp fra sjøtrafikken er jakten på et skips effektivitet avgjørende. I sjøen er bølger ansvarlig for ekstra motstand og øker energien som trengs for å bevege skipet fremover. Ekstra motstand er definert som forskjellen mellom den totale motstanden til et skip underveis i sjøen og motstanden i stille vann. Et skips baug har en

Evaluation of resistance increase and speed loss of a ship in wind and waves

Journal of Ocean Engineering and Science, 2016
Given the indication of the IMO’s intent to the application of the EEDI and EEOI, the complete and precise total resistance of a ship and induced speed loss in wind and wave is primarily required.

Development Of A Semi-Swath Craft For Malaysian Waters [PDF]

, 2006
Small Waterplane Area Twin Hull (SWATH) and Catamaran vessels are known to have more stable platform as compared to mono-hulls. A further advantage of SWATH as compared to Catamaran is its smaller waterplane area that provides better seakeeping ...
