Somewhat belatedly, I’m posting a summary of my thesis on this blog, to summarise what I spent over 3 years of my life working on. I think after finishing my corrections I had had enough of writing for a while. I also started my new post at the university around the same time, so was busy with that, and somewhat lost interest in this site. I’ve copied below both the lay summary to explain the work in more general terms, together with the more technical abstract of my thesis. If you are really interested, the full thesis is available in the Edinburgh Research Archive. Continue reading “My Thesis: Combined wave-current scale model testing at FloWave”

This paper was published in the Ocean Engineering journal in October 2017. It was a joint piece of work with fellow IDCORE researcher at FloWave, Sam Draycott, building on our separate areas of research. In it, we demonstrate the capability of the FloWave facility to generate complex wave-current conditions, and also highlight the importance of considering even relatively low tidal currents when testing wave-energy devices.

With about nine months to go until I am due to hand in my thesis, I am periodically cycling between optimism and pessimism as to how I am progressing. I know that I have managed to pull together a reasonably solid body of work, which my supervisors assure me will be sufficient to complete my doctorate. There is still the small matter of finishing this off, and writing it up in a coherent manner, which I know will take time and effort, but I do still have a few months for this.
That said, there is a nagging concern that I’ve not done enough. I have often heard it said that after a Ph.D., one knows everything there is to know about a tiny specialised area of knowledge, having pushed the boundary of human knowledge in a small but measurable way. This feels like the opposite to my research — I have looked at quite a broad range of topics, but covered none of them in that much detail, or so it seems.
As I am working towards an Engineering Doctorate (Eng.D.) it needs to be focused on the requirements of the sponsoring company, and as such producing a portfolio of work is quite normal, as far as I understand. I am also lucky to be based at a new and unique facility, working in a relatively little studied area of marine energy. Therefore it is perhaps easier in some respects to do novel research, as fewer people have already published on similar topics. Conversely, my research doesn’t fit into a well defined gap in existing knowledge, so setting limits on what is and isn’t important becomes more critical in order to produce a coherent piece of work. In the words of Steve Jobs, there’s always “one more thing”.
The insomnia isn’t helping though…
I realise that I’m very much overdue an update on my research progress, having posted very little so far and nothing in the last year.
Things are generally going well, although I still feel there is a lot to do and only a limited amount of time to do it in. This feeling of pressure is probably due to my colleague Sam, who is a year ahead of me in the IDCORE programme, frantically trying to get his thesis finished off this week. I know that I don’t need to be at the same stage as him — that I have 12 months of funding left — and that I am fairly well advanced with my research. But that doesn’t stop the nagging feeling of not having enough time left.

Thoughts about my 2015 trip to Nantes where I presented my research at the EWTEC conference.
At the start of September 2015, I travelled to Nantes in western France, to attend the 11th European Wave and Tidal Energy Conference (EWTEC). As part of the conference, I presented my research on measurements of the current generation in FloWave. Continue reading “European Wave and Tidal Energy Conference, Nantes”
I have been working towards the first outputs from my research, which will be at a couple of academic conferences this year.
Firstly, I will be presenting a poster at the European Geosciences Union General Assembly 2015 in Vienna, on the work we have been doing on “Wave-current interactions at the FloWave Ocean Energy Research Facility”. This will be in Session NP7.3 on Wednesday 15th April, just in case you happen to be there, do drop by and say hello. I feel slightly intimidated to be presenting as part of a session on non-linear physics of wave-current interactions, as this is not my speciality by any means. But hopefully people will be interested by the potential for interesting research at FloWave, as this is more what I have concentrated on.
The other main piece of work I have been busy with is a paper for the European Wave and Tidal Energy Conference (EWTEC), in Nantes this September. This is on the initial characterisation and spatial variability of the currents generated at FloWave. Again, I think the interesting and novel aspect of this topic is more focussed on the facility, rather than my analysis, but I have got a good chunk of data to present and discuss.
More details to follow once I have finished this work, and actually get to publicly present it. So far I’ve only had to present the outline of my work at an internal event, which hardly counts as a proper academic grilling!
