Over 60 members of the fluid structure interactions group attended the annual summer awayday at the Wide lane sports ground. As part of the event the annual staff-student cricket match took place although was rained off after the PhD students had made an impressive start with their batting especially given only their team captain had ever played cricket before they came to Southampton. The staff side fielded well and were ably assisted by some of the undergraduate summer interns some of whom had played cricket before! The afternoon started with an excellent BBQ provided by Uptons and it was disappointing that the rain came in at 4pm to curtail the game. This annual match has been played for well over three decades originating as a game between ship science staff and the 2nd year undergraduates but more recently has evolved into an opportunity for all staff and phd students to get together.

July saw over 70, year 12 students visit and stay at the University to learn about Ship Science.
The Design Triathlon Summer School saw students design, build, test and race speedboats – learning all about hydrostatics, hydrodynamics and the design process. While the Marine headstart course saw students design, build and test tidal turbines – learning all about renewables, ship science and marine engineering.
Thanks to all those or participated and helped out over the week – it was great fun for all – just see the pictures and videos!

Just a quick series of videos demonstrating the initial use of the waves in the new hydromechanics basin at Southampton.
a) a large regular wave
b) oblique waves
c) an on-board view
d) moored frigate model in severe seas
Many thanks to Dr’s Bennett and Downes for running these tests  and to Dr Bennett in putting these videos together,  along with the rest of the Ship Science team in hosting the Open Day visits on the 3rd and 4th July. The next University open days at which the tank will be available for a visit is on Saturday 5th and Sunday 6th September. Please remember to register via the University open day website. For those with an interest in general engineering, aeronautical or mechanical engineering you can also sign up to visit the ship science activities.

The last month has been a busy one for the new wave and towing tank . Approximately 140 water tankers (bowsers in the correct parlance) came and went leaving behind 3000 tonnes of pure Otterbourne water.   Carriage installation time lapse….
The first proper use of the wave makers occurred last week and they can create some large waves which is very exciting. We are hoping to demonstrate these at the next University open days at the end of this week all day  on Friday 3rd and Saturday 4th.  We are very keen to promote our ship science degree programmes to prospective students  so please feel free to let friends and family know of this opportunity.
We are doing regular tours of the new tank, talks about ship science, tours of our new building (B176)and its new labs as well as the

Faculty Design Show in B177.  The new tank is in B185, all on the new Boldrewood campus co-located with Lloyd’s Register’s Global Technology Centre. Just pop in and have a chat with the staff and students around.
As usual in a small discipline we find it difficult to get the message out about the fascinating careers and excellent salaries to hard pressed schools and their students so any help our friends can do in this respect is much appreciated. The next Open day opportunity is in early September.
We are more than happy for members of staff to visit schools to give talks or for a school group to visit us. Please contact our admissions teams, led by Dr Dominic Taunton, if you would like to discuss these opportunities.

This year the 6th International Conference on Marine Engineering was held in Rome. The conference spanned three days with three parallel sessions, aiming to bring together scientists working on computational methods for maritime engineering. Presentations came from various backgrounds, including naval architecture, offshore engineering, coastal engineering, renewable energy, underwater structural engineering and fish farming. Most attendees were from a computational fluid dynamics background, though with a great variety of methodologies. Whilst viscous-flow finite volume codes were the most represented, there were interesting results from smooth particle hydrodynamics and Lattice-Boltzman methods. There were several plenary lectures which focused on fluid-structure interactions and complex viscous modelling of bubbly flows and breaking waves.
Across all fields and methodologies there were some similar themes. Accurate viscous modelling, adaptive mesh technologies and hardware-software interaction were key topics throughout. In naval architecture, much of the discussion was focused on accurate manoeuvring simulations in waves, design & optimization and the use of advanced turbulence modelling.
The University of Southampton had two attendees: Ameen Bassam presented on “Ship Voyage Energy Efficiency Assessment Using Ship Simulators” and James Hawkes presented on “Chaotic Linear Equation-System Solvers for Unsteady CFD”.
The next MARINE conference will be held in Nantes, France, in 2017. Full papers from this year can be downloaded from:

Marion James, a FSI PhD student based in our Performance Sports Engineering Laboratory (PSEL) at the University of Southampton while on holiday in the USA last month was pleased to see the outcome of some performance testing undertaken awhile back in the University of Southampton Jubilee Pool. She commented, ‘Speedo USA asked us to drag-test and evaluate the performances of several products to support the training programme of high-level swimmers, and especially sprinters. As a result, two products ‘Dragster’ and ‘Dragtini’ are now available on the US market. They act as a parachute to increase the swimmer’s drag during a training session in order to provide higher intensity training and power-up swimming performances.
PSEL has been looking into swimming drag over the last six years. A recent paper in Journal of Sports Engineering and Technology by  lead author Angus Webb looks at how repeatable techniques are for measuring a swimmer’s resistance when towed passively
 

Progress has gone well since the hand over of the new fluids laboratory building from the main contractors in early March. The passive beach at the east end has been installed along with the active side beaches on the south wall. The components of the main carriage started arriving this morning and should be assembled over the next two weeks.
1st June is scheduled for the start of tank fill with a cautious process with 3000 tonnes of water required. This gives a week for us to prepare demonstrations using the wavemakers for the university open day on the 3rd and 4th July. We are looking forward to showing visitors around as well as making a start on a number of research projects.
We are delighted to announce that our Towing tank manager, Bertrand Malas has now started work and will be delighted to discuss future use of the facility as progressively more of its capabilities become available.

Prof Stephen Turnock and Dr Jon Downes from the Maritime Robotics Lab attended the kick off meeting of the EUH2020 projects BRIDGES in Paris recently. This 4 year, 8Meuro project aims to develop two deep water gliders.
Autonomous underwater gliders use a device, similar to a fish’s swim bladder to alter their buoyancy and  glide on wings either upwards or downward depending on whether they are lighter or heavier than water.  They are very energy efficient and can carry out tasks that last for months and can travel large distances.
A video gives an overview of the project by one of the 19 project partners Armines. The University of Southampton’s work will concentrate on the hydrodynamic design of the external shape of the hull and an auxiliary hybrid propeller for seabed survey at depth. This builds on our expertise in CFD and testing of AUVs such as Delphin2 using wind tunnels and towing tanks.

Dr Dmitriy Ponkratov Senior Consultant at LR will be presenting this interesting LR/SMMI
Abstract
Despite of the fact that full scale measurements look like the most realistic, there are a lot uncertainties (hull roughness, wind, waves, current, water depth) which may affect the results. Moreover, they are usually scarce and even when available they are incomplete for validation purposes. Model tests can help to avoid these uncertainties as it is possible to simulate pure calm conditions in towing tank. However, the results can be again not realistic because of the scale effect. CFD has a possibility to calculate ships in full scale avoiding any scaling problems, but the numerical methods should be carefully validated, ideally against full scale measurements. So It can be concluded that only investigations in all three directions can help to better understand the fluid dynamic problems.

Two FSI members of staff, Dr’s Nick Townsend and Adam Sobey were present during the filming.  Celsius Tan the Executive Assistant from IHPC – SMMI Joint Lab reports that on the 17^th March 2015, IHPC – SMMI Joint Lab venue was chosen to be part of a short video by A*STAR Corporate Communications to showcase the significance of the marine sector for Singapore’s economy, and the importance of R&D in the shipping industry. A*STAR Corporate Communications notes that the film.
The film will take a narrative approach that is inspired by movie trailers.  This allows us to move quickly through a topic, with sequences which can be highly stylized and exciting. This video will have a slightly grander scope, looking at location shooting in the research labs as well as at a shipyard. 
The following points will be brought into the script mix, adding the educational and emotional content to the story: 

• Singapore is a seafaring nation

• Partnerships and collaborations are important to research

• Rising costs and competition mean that ships will have to be more efficient as well as durable.  At the end of a ship’s lifespan scrapping has great environmental and human cost 

 

• The marine sector is a significant engine of Singapore’s economy.
