Description

College of Engineering, Mathematics and Physical Sciences - Engineering Seminars 2018 / 2019

Multiple dates from: Monday 5 November 2018 - Wednesday 5 June 2019

Venue: Harrison Building, North Park Road, Streatham Campus, EX4 4QF

Event Information

The aim of the College of Engineering, Mathematics and Physical Sciences - Engineering Seminars is to enhance our inter-centre communication and encourage research collaboration. We invite internal or external speakers to talk about the exciting areas of their work and the potential future areas of work for collaboration. The seminars generally take place at 13.30 on the first Wednesday of each month during term time.

However, the date/time for external speakers can be flexible. Each speaker will present for about half hour, followed by fifteen-minute Q&A.

Afterwards, attendees can continue their discussions and enjoy a biscuit and coffee/tea in the same room.

Please see below for full event details.

Schedule

Date and time: Monday 5 November 2018, 14.30 - 15.30

Speaker: Dr Colin Caprani, Monash University, Australia

Topic: Traffic Loading & Bridge Management

Venue: Harrison 171 (changed from Harrison 203)

Synopsis: In this talk I will proceed from a consideration of societal and structural engineering risks to show the role that the modelling of highway bridge traffic loading has in the management of existing bridges. This talk covers disciplines of structural reliability, structural dynamics and traffic engineering and so should be of interest across traditional discipline lines.

Biography: Dr Colin Caprani is the Director of Teaching and a senior lecturer in Department of Civil Engineering of Monash University, Australia. He is a Chartered Professional Engineer (CPEng MIEAust) and Chartered Structural Engineer (CEng MIEI, MIStructE) with considerable industrial and academic experience. He has worked as a design structural engineer on a wide range of projects, including integral bridges, new-concept bridge beam development, large-scale commercial mixed-use developments, and renovation and refurbishment of listed structures. His research specializations involve highway bridge traffic loading for short- and long-span bridges; vibration serviceability of footbridges; structural reliability and statistics of extremes; and Intelligent Transportation System – infrastructure interaction. He has lectured on numerous courses in three universities.


Date and time: Wednesday 7 November 2018, 13.30 - 14.15 including a question and answer session, followed by further discussion in the same room 15.30.

Speaker: Prof. Gavin Tabor, University of Exeter

Topic: Computational Fluid Dynamics: an Exeter Perspective

Venue: Harrison 170

Synopsis: Computational Fluid Dynamics is the solution of fluid dynamics problems using computers, typically in 2 or 3 spatial dimensions. Its use in engineering has grown inexorably over the last 20 years, fueled by the constant growth of computing power, and practically every engineering discipline has been impacted by the ability to perform predictive physics-based simulations of everything from heat transfer, combustion and reaction to multiphase and free surface flow.

In this seminar I intend to provide a personal viewpoint of the state of the art, and review four main aspects of the work from my group; OpenFOAM, research with the company Hydro International, scour and sedimentation, and optimisation through machine learning-driven CFD.

Biography: Prof Gavin Tabor joined the University of Exeter in 1999 after 5 years at Imperial College as a PDRA. Whilst at Imperial he was part of the informal team developing the FOAM code, now released as OpenFOAM; this has formed the core of his research programme here in Exeter, building a research team currently numbering 10 researchers and drawing on both industrial and EPSRC funding. During his 25 years experience in CFD he has worked on a range of techniques and areas including turbulence modelling, multiphase flow and combustion, and application areas including biomedical, SUDS, renewable energy, additive manufacture and optimisation.


Date and time: Wednesday 5 December 2018, 12.30 - 13.15

Speaker: Prof. James Brownjohn, University of Exeter

Topic: Structural condition assessment and performance of rock lighthouses around the British Isles

Venue: Harrison 170

Synopsis: EPSRC funded project STORMLAMP started in 2016 with modal (vibration) tests on a set of seven remote masonry towers perched on rocky outcrops around the British Isles. The project operates with very good teamwork between Plymouth (led by Alison Raby, experimental hydrodynamics and CFD), UCL (led by Dina D'Ayala, numerical structural modelling) and Exeter (led by myself, field testing and monitoring) with very strong technical and research support. While it's been a fun and photogenic project there have been several technical and logistical challenges and some interesting research outcomes. We've established the extreme high quality and robustness of the 19th century construction and the different behaviour of the 20th steel helidecks. We've worked out what lighthouse keepers meant when they said the structures seemed to rock during storms and we are getting a feel of the level of wave loads that cause this behaviour. The project has other benefits e.g. in terms of system identification uncertainty due to axisymmetry, and methods of characterising breaking wave loads on marine coastal structures.

Biography: James joined the University of Exeter as part of the Vibration Engineering Section in 2013. He has BSc in mechanical engineering (Bristol) and PhD in earthquake engineering (Bristol). After a few years with MoD, offshore oil/gas and coding he began an academic career in Bristol, then Singapore (where he learnt what fun you can have doing consulting work), then Plymouth, then Sheffield, then wound up in Exeter.


Date and time: Wednesday 16 January 2019, 13.30 - 14.15

Speaker: Prof. Prakash Kripakaran,University of Exeter

Topic: Flood resilience of bridge structures: Scour and hydrodynamic forces due to debris blockage

Venue: Harrison 170

Abstract: The talk will present research undertaken as part of the EPSRC-funded project - “Risk assessment of masonry bridges: Hydrodynamic impacts of debris blockage and scour”. Debris, which can worsen scour and increase hydrodynamic forces, is a leading cause of bridge failure in the UK and internationally. This project has characterized the scour and hydrodynamic effects of debris blockage through a combination of laboratory experiments and numerical (CFD) modelling. Results indicate that debris can amplify scour by a factor of 3, and highlight particularly the importance of paying attention to debris-induced scour in low flow conditions when bridges are often considered to be not at risk. The approach developed for assessing scour risk is in the process of becoming embedded within current guidance for practitioners, and is also being used by an industry partner via a secondment.

Biography: Prakash Kripakaran is a senior lecturer in structural engineering and academic lead for the civil and structures research group. He has an undergraduate degree from the Indian Institute of Technology, Madras, and a MS and PhD from North Carolina State University. Prior to joining Exeter in 2010, he worked as a postdoctoral researcher at EPFL in Switzerland. His research interests are mainly in the use of innovative sensing and computing techniques for maintenance and management of bridges.
