Polymers, Plastics, Rheology and Processing
This web site is about a range of subjects on Polymers, Plastics, Rheology and Processing and covers a research period from the 1970s to 2020. A significant amount of the work is visual and for example the movie clips on this page show in one case, stress fields in flowing molten polyethylene plastic and the second movie shows how water filaments break up when subject to very high stretching extensional strain rates. The site hopefully will prove useful to people who want relatively simple and often visual explanations about a range of scientific and engineering topics.
There are specific sections on;
You will find short introductions to each of the headline topics followed by a selection of presentations that describe different aspects of the various scientific and technological fields. There are also my Cambridge University lecture notes on both;
Work on filament breakup carried out in conjunction with CEMEF at Sophia Antipolis, France in the 2000s, can be found at;
Science, Engineering and innovation all have visual and creative parts and some aspects are covered in“Something to say”. The section includes short articles such as how scientists and engineers can be thought of as creative people in addition to a range of topics that could be classified as opinions rather than scientific facts. There is a cluster of very visual Movie clips ,again most of the movies involve flow describing various processes and experiments. I have also added a 2000s section on plastics use and reuse;
Stretching Rheology and Symmetry to the limits!
Covid-19 resulted in a 2020 Institute for Non Newtonian Fluid Mechanics (INNFM) Port Merrion (Wales) meeting to be cancelled and so below I include the contribution that I would have given. The talk is a story that links my connections with Wales and highlights two areas of research one carried out in the 1970s and the other in the 2010s. There are notes for each slide
Process and Product Innovation was an important part of our work and you will find sections on several separate inventions.
If you are looking for a scientific/technology story to read, why not try my fiction novel? The book was written in the 1990s with an epilogue added in the 2000s. I wonder if you can pick up how the world had changed between these dates, even after such a relatively short period of time?
The scientific research described in this web page has either been created by myself or an army of Postoctoral or PhD students working with me at Bristol, Sussex, CEMEF (France) and Cambridge. I am indebted to all their talents in contributing to this work and acknowledge their invaluable contribution. Any publications that appear on this web site are for educational purposes only.
