Dr Simon Hogg, BSc PhD CEng FIMechE

(email at simon.hogg@durham.ac.uk)

Simon Hogg returned to academia in January 2010 taking up a position as Reader in the School of Engineering and Computing Sciences. He is a mechanical engineer with specific expertise in analytical, experimental and computational fluid dynamics, turbomachinery, aerodynamics, thermodynamics and heat transfer. His research interests lie in the general areas of turbomachinery component development for improved thermal performance and power cycle/distribution modelling & optimisation.

Simon graduated with a BSc and PhD from University of Manchester (UMIST) in 1980’s. His PhD study was funded by Rolls Royce and concerned developing computational fluid dynamics codes for predicting gas turbine swirl stabilised combustor flows. Following graduation he held University posts for 10 years, both as a Rolls Royce funded Research Fellow at Oxford University and then later as a lecturer in Engineering at Leicester University. Whilst working in Universities he developed research interests in turbine aerodynamics and turbine bearing and sealing systems. This work involved experimental, computational and analytical studies including developing new test facilities and new fast-response instrumentation techniques, for measuring unsteady turbomachinery flows.

In 1998 he joined ALSTOM’s power generation equipment supplier division, initially working in Steam Turbine R&D and then, from 2003 to 2010, in the Company’s Steam Turbine Retrofit Business. During this period he held senior management/technical leadership positions in Tendering and eventually as Engineering Director of the Turbine Retrofit Business.

Simon is a Fellow of the Institution of Mechanical Engineers. He sits on European (BSI/IEC) and American (ASME) international steam turbine codes and standards committees.
