research interests

Professor Hewitt has worked on a variety of subjects in the general field of chemical engineering but his speciality for several decades now has been in multiphase flow systems, with particular reference to channel flow and heat transfer. Multiphase flow consists of the flow of more than one phase (solid, gas or liquid) and is exemplified by the flow of steam-water mixtures in boiler tubes (two-phase flow) and by the flow of oil/water/natural gas mixtures ('three phase flow') in North Sea pipelines. Professor Hewitt has published many papers and books in this industrially important area and has lectured on the subject widely throughout the world. He has had a wide experience of industrial application through his founding of the Heat Transfer and Fluid Flow Service (HTFS) at Harwell and through extensive consultancy and contract work. Professor Hewitt's contributions to the field have been recognised by his election to the Royal Society, the Royal Academy of Engineering and the US National Academy of Engineering in addition to international awards.
