Estimation of Added Resistance of a Ship in Regular Waves

Brodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2011
Two methods of added resistance calculation are briefl y presented, one developed by Faltinsen, and the other by Salvesen. Both are based on the Salvesen, Tuck and Faltinsen linear strip theory, as they use it to defi ne the wave induced motions. The fi rst one obtains the added resistance by direct pressure integration, while the second one involves ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

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.

A Boundary Element Method for Motions and Added Resistance of Ships in Waves

Transactions of FAMENA, 2015
The accurate prediction of ship resistance in waves is nowadays of increased importance since it greatly influences ship performance regarding sustainable service speed and fuel consumption in seaways. Added resistance is considered as the longitudinal component of the second order mean force acting on a ship in waves and can be calculated from the ...

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Robust Electrocaloric Performance Enabled by Highly‐Polar Frustrated Nanodomains in NaNbO3‐Based Ferrodistortive Relaxor

Advanced Functional Materials, EarlyView.
P4bm framework in NaNbO3‐Ba(Ti, Hf)O3 ferrodistortive relaxor entails short‐range and highly‐polar ferrodistortive orders. The abundant highly‐polar orders facilitate to increase entropy change, and robust octahedral oxygen tilt enables to impede thermal perturbations.

Influence of Bow Flare Shapes on Added Resistance in Waves

Journal of the Japan Society of Naval Architects and Ocean Engineers, 2010
Added resistance in waves is a predominant component for the estimation of ship speed in actual seas, so that it is necessary to be calculated accurately. The added resistance in waves is influenced by the hull form above water line. However it is difficult to take into consideration the form to the calculation theoretically.
