Staff Profile

Emeritus Professor Mike Reeks

Emeritus Professor



Professor Mike Reeks is  Professor in Multiphase Flow. He was recently a Marie Curie Senior Research Fellow at the European Research Centre at Ispra, Italy. Most of his career however has been spent in the nuclear industry, first with the Central Electricity Generating Board (CEGB) and then with Nuclear Electric and Magnox Electric during which time he was head of the aerosol physics and containment thermal hydraulics group. His primary research interest is in the modelling of dispersed flows where he has pioneered the development of the PDF approach to two-fluid modelling.
