John Young’s research expertise is in thermodynamics and fluid mechanics. He has worked for many years on two-phase flows in steam turbines, a strikingly diverse subject that has stimulated his interest in other fields such as turbulent particle transport and deposition, homogeneous nucleation and chemical vapour deposition. He has also worked on the thermodynamics of power generation cycles (including the cooling of gas turbine blades), the modelling of solid oxide fuel cell systems and multi-component diffusion. Most of this work is connected in some way to the power generation industry but he is also interested in fundamental problems which have a broader range of application.
John Young's research projects have varied from analytical theoretical work to multi-phase computational fluid dynamics (CFD) for specific applications. He has also been involved with a number of experimental projects but could hardly be described as an experimentalist. Over the years he has contributed research papers in the following areas:
- Non-equilibrium thermofluid dynamics of two-phase flows with phase change.
- Homogeneous nucleation and the microscopic theory of droplet growth.
- Wet-steam turbines (non-equilibrium CFD methods, wetness losses, etc).
- Jet engine performance degradation due to droplet nucleation and water ingestion.
- Thermodynamic analysis of advanced power generation plant.
- Thermodynamics of blade cooling in gas turbines.
- Transport and deposition of small particles in turbulent flows.
- Modelling of solid oxide fuel cells.
- Multi-component gas diffusion.
- Corrosive salt vapour deposition in coal-fired gas turbines.
John Young is the Hopkinson and ICI Professor of Applied Thermodynamics and a professorial fellow of King's College. He read Engineering Science at Christ Church, Oxford from 1966-69, and obtained his Ph.D. from Birmingham University in 1973. In 1976 he joined the Engineering Department at Cambridge and worked at the Whittle Turbomachinery Laboratory until 1999 when he moved to the Hopkinson Laboratory on the main site.
