Department of Chemical Engineering and Biotechnology


The 30th International Symposium on Combustion took place at the University of Illinois, Chicago on July 25th-30th 2004. This is the major conference for combustion research and is held every two years. It is highly competitive and less than half of the submitted papers were accepted, yet fifteen people from the Department of Chemical Engineering, Cambridge University attended and presented six papers.

An award was made to Professor Hayhurst at the Banquet for his long service to the Combustion Institute, particularly for his ten years editing Combustion and Flame.

The Department is a major international player in the combustion world - research on combustion, energy conversion and pollution control has grown within the department to become one of its major activities.

The people who attended from the Combustion Group were Prof Allan Hayhurst, Dr John Dennis, Dr. Paul Fennell, Stuart Scott, Alasdair Campbell and Andrew Rees.

From the Computational Modelling Group, Dr Markus Kraft, Amit Bhave, Jasdeep Singh, Neal Morgan, Sebastian Mosbach (and Michael Balthasar, now at Volvo)

The papers presented were:
J. Hult*, U. Meier, W. Meier, A. Harvey, C.F. Kaminski
Experimental analysis of local flame extinction in a turbulent jet diffusion flame by high repetition rate two dimensional laser techniques and multi-scalar measurements

J. Hult, I.S. Burns*, C.F. Kaminski
