A Zonal CFD Approach for Fully Nonlinear Simulations of Two Vessels in Launch and Recovery Operations

Investigators: Dr Ling Qian (PI), Prof Derek Causon and Prof Clive Mingham

Researcher(s): Dr Zhihua Ma

Funding body and Value: EPSRC (EP/N008839/1), £317,832

Starts: 1st October 2015 Ends: 30th of September 2018

Project Summary: Launch and recovery of small vehicles from a large vessel is a common operation in maritime sectors, which is often performed in harsh sea conditions. The recent User Inspired Academic Challenge Workshop on Maritime Launch and Recovery, held in July 2014 and coordinated by BAE systems, identified various challenges associated with safe launch and recovery of off-board, surface and sub-surface assets from vessels while underway in severe sea conditions. This project will address these issues by developing an accurate and efficient numerical model that can be applied routinely for the analysis of the motion and loadings of two bodies in close proximity with or without physical connection in high sea-states.

Virtual Wave Structure Interaction (WSI) Simulation Environment

Investigators: Dr Ling Qian (PI), Prof Derek Causon and Prof Clive Mingham

Researcher(s): Dr Pedro Martinez Ferrer

Funding body and Value: EPSRC (EP/K037889/1), £323,344

Starts: 31st October 2013 Ends: 30th October 2016

Project Summary: The project is a close collaboration between MMU, University of Plymouth (UoP) and STFC-RAL with significant experience in research into wave interactions with fixed and floating structures. The aim is to develop integrated parallel code implemented on a massively multi-processor cluster and multi-core GPUs providing fast detailed numerical wave tank solutions of the detailed physics of violent hydrodynamic impact loading on rigid and elastic structures. The project is linked to and part of a carefully integrated programme of numerical modelling and physical experiments at large scale. Open source numerical code will be developed to simulate laboratory experiments to be carried out in the new national wave and current facility at the UoP.

Project title: A CCP on Wave/Structure Interaction: CCP-WSI

Investigators: Dr Ling Qian, Prof Derek Causon and Prof Clive Mingham in collaboration with Plymouth, City, Bath and Exeter universities and STFC-RAL.

Funding body and Value: EPSRC (EP/M022382/1), £483,159

Starts: 1st October 2015 Ends: 30th September 2020

Project Summary: The project is to establish a new Collaborative Computational Project (CCP) serving the UK research community in the area of wave structure interactions (WSI). The new CCP-WSI will bring together computational scientists, Computational Fluid Dynamics (CFD) specialists and experimentalists to develop a UK national numerical wave tank (NWT) facility fully complementary to existing and future UK experimental laboratory facilities for marine, coastal offshore engineering and thus support leading-edge research in an area of high national importance. The proposed CCP-WSI would extend the framework and methodology for sharing and future proofing EPSRC funded code developments in wave structure interaction to the wider community. This is proposed through a programme of community events and activities, which are designed to foster the links between experimentalists and those performing computations, between industry users, academics and the interested public.

Project title: FROTH: Fundamentals and Reliability of Offshore Structure Hydrodynamics

Investigators: Dr Ling Qian, Prof Derek Causon and Prof Clive Mingham

Researcher(s): Drs Zhihua Ma and Hanbin Gu

Funding body and Value: EPSRC (EP/ J012793/1), £241,712

Starts: 1st November 2015 Ends: 31st October 2015

Project Summary: The FROTH project is a close collaboration between five universities with significant experience in research into wave interactions with fixed and floating structures working together to combine and apply their expertise to different aspects of the problem. The aim is to investigate the detailed physics of violent hydrodynamic impact loading on rigid and elastic structures through a carefully integrated programme of numerical modelling and physical experiments at large scale. Open source numerical code will be developed to simulate laboratory experiments to be carried out in the new national wave and current facility at the UoP. At MMU, we will mainly look into the effects of aeration (both entrapped pockets and entrained bubbles) on the flow characteristics and peak values of impact loads.

Project title: Modelling Marine Renewable Energy Devices; Designing for Survivability

Investigators: Dr Ling Qian, Prof Derek Causon and Prof Clive Mingham in collaboration with Imperial College and Queen’s University of Belfast

Researcher(s): Drs Hanbin Gu and Zhihua Ma

Funding body and Value: EPSRC (EP/J010197/1), £ 1,039,617

Starts: 30th June 2012 Ends: 29th December 2015

Project Summary: The primary aim of the project is the assessment of the extreme wave loads on WECs using numerical models validated against experimental observations and full-scale prototype data. The project team combines institutions with significant experience in research into extreme waves (Imperial College), wave energy converters (Queen's University Belfast) and numerical modelling (Manchester Metropolitan University), forming a strong and well-balanced consortium. They will be supported by a steering committee comprising a number of key industry practitioners and stakeholders, bringing in a wide range of backgrounds from device developers, certifying bodies and the offshore industry. The results of the numerical models will be analysed to provide guidance on the appropriateness of particular models, as well as issues associated with the scaling of extreme loads. This will enable an estimation of the uncertainty in extreme loads based on the modelling technique adopted.
