MIXED CONVECTION HEAT TRANSFER
Brief Review of the Fundamentals, State of the Art and Design Procedures
Prof. J. D. Jackson
University of Manchester, UK
Summary
Mixed convection is an important mode of heat transfer in which interactions between free
and forced convection occur as a result of buoyancy-induced motion. These cause the
effectiveness of heat transfer to be modified in a surprising manner which, potentially, can
have serious practical consequences. Mixed convection is encountered in a variety of
industrial applications, notably, nuclear and conventional power generation, electronic
systems cooling, air conditioning and ventilation, food and chemical manufacturing and gas
turbine systems. This short presentation on mixed convection will be given by Professor
J.D. Jackson of the University of Manchester, UK, an internationally recognised expert on
the subject who, through his research, has contributed extensively to the present
understanding of buoyancy-influenced convection. He has recently completed a detailed
report on mixed convection research which provides a wide-ranging and up to date picture of
the state of the art and of practical design procedures. This material has been offered as a
one day ‘in house’ training seminar at a number of companies and research organizations in
the UK and elsewhere. It was presented in a form suitable for engineers and scientists
having some prior knowledge of heat transfer but not necessarily an in-depth understanding
of the subject. In the present short lecture at Tsinghua University he will give an outline of
the material covered in the one day training seminars.
About the Speaker
Prof. Jackson is from the University of Manchester in the UK. He is an expert on fluid flow,
heat transfer applied to nuclear reactors. His work on the effects of non-uniformity of fluid
properties on convective heat transfer to gases liquids and also fluids at supercritical pressure
was followed by studies of mixed convection, transient turbulent flow, radiative heat mission
and of problems involving boiling, condensation and evaporation. In addition he was
responsible for an extensive programme of research on heat transfer to liquid sodium and the
characteristics and scattering properties of argon/sodium aerosol mixtures. In recent times
Prof. Jackson has concentrated his attention on thermal aspects of very advanced nuclear
reactor systems (Generation IV reactors). He currently sits on the Advisory Panel of the EU
funded project on High Performance Light Water Reactors and has just joined the newly
initiated IAEA Coordinated Research Programme (CRP) on Advanced Water-cooled
Reactors. |
