TRANSNAV 2021

March 19, 2021 admin_clem 14

14^th International Conference on Marine Navigation and Safety of Sea Transportation

The Conference is organized by the Faculty of Navigation of the Gdynia Maritime University and The Nautical Institute.

The Conference is addressed to scientists and professionals in order to share their expert knowledge, experience and research results concerning all aspects of navigation, safety of navigation and sea transportation.

The 14th Edition of the World conference on maritime transport research designed to find solutions to challenges in waterborne transport, navigation and shipping, mobility of people and goods with respect to energy, infrastructure, environment, safety and security as well as to the economic issues.

AIRCOAT team will be presenting its last scientific paper: Validation of a Flow Channel to Investigate Velocity Profiles of Friction-Reducing Ship Coatings.

In this paper we validated the methodology by determining the velocity profile of the flat channel wall (without coatings) and comparing to a custom build CFD model in OpenFOAM. Preliminary results show that flow velocity along the longitudinal axis are in general accordance with experimental results.

About

The reduction of greenhouse gases has played an important role in the 21^st century in limiting climate change. Yet with the increase in the international transportation of goods, with most of these goods being transported by ships, we need new technologies in order to maintain these reductions in emissions.

As part of the EU Green Week Partner Events, this webinar will give insights into the development of the surface structure and test results. We will demonstrate how the size, geometry, and chemical properties of the surface structure play a crucial role in creating air lubrication.

Depending on the type of ship used for transportation, more than 50 % of the energy required for propulsion – which is approximately 70% of the total fuel usage – is used to overcome frictional resistance. This resistance occurs due to the friction between the ship hull and water. A reduction of this resistance offers the possibility of a substantial decrease in fuel consumption and subsequently the emission of greenhouse gases.

To respond to that challenge, AIRCOAT H2020 project is developing a foil system to be applied to ship hulls. The surface structure of the foil aims to retain air when submerged under water, a system that reduces the frictional resistance of ship.

The project is inspired by observing nature. In particle the floating fern Salvinia molesta, a plant able to retain a thin layer of air when submerged under water. The surface of S. molesta features natural, water-repellent (hydrophobic) hairs with water-attracting (hydrophilic) tips, combining to enable the retention of air. Due to the lower viscosity of air in comparison to water, an air layer applied to a ship hull can reduce the friction resistance. This method is called ‘air lubrication’.

The AIRCOAT foil surface structure is designed and produced from small samples all the way up to pilot test scales. These have been tested in different experimental and numerical setups to determine drag reduction, anti-fouling, and air layer stability.

It embraces a balanced selection of about 11 Members chosen according to their area of research and work performed and who are the cornerstone of the shipping and ports research network.

IStC Members were individually invited ‘ad personam‘ by the Conference Chairman. The IStC function is to provide guidance and assistance to the Local Organising Committee and contribute to the publicity and promotion of the 2021 World of Shipping Portugal, an International Research Conference on Maritime Affairs.
Maintaining the quality of submitted research papers, and an appropriate balance between the interests of researchers and practitioners, are also particularly important goals.
