Before gaining his PhD, Lyes Khezzar obtained a BEng in mechanical engineering (1st class honours) from Bradford University and an MSc from UMIST. He has a wide professional experience that spans both industry and academia.

He has participated in a variety of research and consultancy projects sponsored by major industrial bodies and government agencies from the UAE, UK, US, Oman and Algeria that span the fields of internal flows in equipment, combustors, turbomachines, gas and water distribution networks and fluid handling facilities.

His main research interest is in the area of application of computational fluid dynamics and laser based techniques to develop and understanding of flows of industrial relevance.  These include multiphase flows in separators and fluid handling equipment, liquid plunging jets, atomization of liquid impinging jets, convective heat transfer in impinging jets using RANS and LES modelling, modelling of convective heat transfer of non-Newtonian, inelastic and viscoelastic flows in ducts and their heat transfer augmentation properties.

He is a fellow of the Institution of Mechanical Engineers and a registered Chartered Engineer
