4th JMSE Webinar

Energy-Saving Devices for Ships

Energy-saving devices for ships have become a subject of intensive research and development in recent times, aiming at reducing fuel consumption and emissions and contributing to Blue Growth. A particular class deals with devices controlling the hydrodynamic flow properties, leading to drag reduction, improving the hull–propeller interaction and the propeller performance. Another important category is based on the exploitation of renewable energy, such as wind, wave and solar to improve the overall ship performance. Many of the developed systems are considered particularly suitable for retrofitting seagoing vessels. The investigation should consider not only the improvement of the calm water performance of ships but also the system operation in realistic sea-states of moderate and higher severity.

The webinar will cover various topics as: Energy-saving devices improving ship hydrodynamic performance; Renewable energy powered marine vehicles; Biomimetic systems and flapping thrusters; Systems augmenting ship propulsion in waves; Experimental and computational ship hydrodynamics etc.

Date: 28 October 2022

Time: 10:00 am CEST | 4:00 am EDT | 4:00 pm CST Asia | 9:00 am BST | 11:00 am EEST

Invited Speakers

School of Naval Architecture & Marine Engineering, National Technical University of Athens, Greece

Diploma in Μechanical Εngineering (2007, NTUA) from National Technical University of Athens and PhD from the same Department and University (2014, NTUA). From 2018 he is an assistant professor at the school of Naval Architecture and Marine Engineering at NTUA. His work includes the development of both mesh and mesh-free (particle) and CFD tools designed for use in High Performance Computing. He is actively involved in the development of finite volume CFD (URANS, LES, DES) solver on unstructured grids of moving/deforming geometries and their application in external compressible and incompressible two-phase flows. His research interests include the development and application of Lagrangian (Particle) methods and their coupling with the grid based CFD methodologies. He has authored 24 scientific articles in refereed journals more than 25 scientific articles in conference proceedings with peer review. Google Scholar h-index 14.

University of Southampton, UK

Dr Townsend is a Lecturer at the University of Southampton, in the Faculty of Engineering and Physical Sciences, Maritime Engineering group. He was awarded a degree in Mechanical Engineering from the University of Birmingham, U.K., in 2003 and an Engineering Doctorate (EngD) degree from the University of Southampton, U.K., in 2008 with the Royal National Lifeboat Institution (RNLI). His research focuses on the dynamics of renewable energy scavenging systems. His research has covered aspects of gyroscopic, pendulum and flapping foil system dynamics for ships, boats and autonomous surface and underwater vehicles, receiving funding from public bodies, charity organisations and industrial sponsors. He was Awarded the Royal Institution of Naval Architects (RINA) Calder Prize and was a runner up in the Royal Academy of Engineering ERA Foundation Entrepreneurs Award. He has authored more than 25 scientific articles in refereed journals and conference proceedings with peer review. Google Scholar h-index 16.
