Application of wave added resistance calculation method in comprehensive optimization design of ship hull form

open access: yesZhongguo Jianchuan Yanjiu, 2020
Objectives In order to obtain a good hull form with both static water and wave resistance performance, a bulk carrier is taken as the research object to carry out the comprehensive optimization design of the hull form.Methods The evaluation of the static

Research on the Hydrodynamic Performance of a Pentamaran in Calm Water and Regular Waves

open access: yesApplied Sciences, 2023
As a typical multi-hull ship, the pentamaran has a wider deck, higher damage stability, and low-speed seaworthiness in harsh sea conditions compared with other multi-hull types such as the catamaran and trimaran, having more potential for becoming a new ...

Systematic Experimental and Numerical Analyses on Added Resistance in Waves [PDF]

open access: yesJournal of the Society of Naval Architects of Korea, 2014
국제적으로 친환경에 대한 관심이 증가하고, 국제해사기구 (International Maritime Organization, IMO)가 선박의 온실가스 방출을 규제하기 위해서 2013년부터 선박연비제조지수 (Energy Efficiency Design Index, EEDI)를 도입하면서 조선 및 해운업계 에서는 선박의 운항 효율이 주요 관심사가 되었다. 선박의 운항 효율을 향상시키기 위한 많은 방법 중에 하나로 파랑 중 저항을 감소시키는 방법이 고려되고 있다.

Analysis of added resistance and seakeeping responses in head sea conditions for low-speed full ships using URANS approach

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2017
The KVLCC2 and its modified hull form were investigated in regular head waves using Unsteady Reynolds Averaged Navier–Stokes (URANS) methods. The modified KVLCC2 (named KWP-bow KVLCC2) is designed for reducing wave reflection from the bow.

Nanorod optical antennas for dipolar transitions [PDF]

open access: yes, 2009
Optical antennas link objects to light. Here, we analyze metal nanorod antennas as cavities with variable reflection coefficients to derive the interaction of dipolar transitions with radiation through the antenna modes.

Optimization of Maintenance Schedule for Containerships Sailing in the Adriatic Sea

open access: yesJournal of Marine Science and Engineering, 2023
Biofouling attaches to immersed surfaces in between hull cleanings. Due to high speeds and relatively short port times, biofilm often attaches to the immersed surfaces of containerships.

Dissecting action sports studies: Past, present, and beyond [PDF]

open access: yes, 2013
The term “action sports” broadly refers to a wide range of mostly individualized activities such as BMX, kite-surfing, skateboarding, surfing, and snowboarding that differed – at least in their early phases of development – from traditional rule-bound ...

Estimation of Added Resistance in Waves in a Ballasted Condition

open access: yesJournal of the Japan Society of Naval Architects and Ocean Engineers, 2010
As for bulk carriers and tankers it is important to calculate added resistance in waves in a ballasted condition with accuracy,because they are operated in ballasted conditions for half of their operation time. However, it is difficult to estimate the resistance with accuracy by the numerical calculation since wave making phenomena in a ballasted ...

Effects of diffraction in regular head waves on added resistance and wake using CFD

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2019
This paper employs computational tools to investigate the diffraction effects in regular head waves on the added resistance and wake on the propeller plane. The objective ships are a 66,000 DWT bulk carrier and a 3,600 TEU container ship.
