Professor Dr.-lng. F. Mayinger
on his 60th birthday

PROFESWR Dr.-Ing.
F. Mayinger, who was born on
2 September 1931 in Augsburg, Germany, celebrated
his 60th birthday on 2 September 1991. We wish him,on this occasion, a healthy and harmonious long life
and we applaud his outstanding contributions
to thefields of thermal and fluid sciences and their applications.
Professor Mayinger studied mechanical engineering
at the Technical University Munich and obtained hisDipl.-Ing. degree in 1955. He started his academic
career in 1956 as ‘Wissenschaftlicher
Assistent’ at theInstitute for Thermodynamics
of the Technical University of Munich under Professor E. Schmidt. At theend of 1961 he received the ‘Doktor-Ingenieur’degreewith a thesis on ‘Measurementsof the viscosity ofwater substance up to 700°C and 800 bar’.
He became in charge of a research department andlaboratory for nuclear- and process-engineering
at theMaschinenfabrik
Augsburg-Niirnberg(MAN) in theNiirnberg works in 1962. In 1969, he was selected
as the Chair professor of process engineering at theTechnical University of Hannover. In 1981, a searchstarted to take the reputablechair for Thermodynamics A as successor of Professor U. Grigull.
Professor Mayinger was the leading candidate and theBavarian Kultusminister
invited him to take the chair.
Now he owns this internationallyknown chair.
Professor Mayinger’s work is published in morethan 150 papers in international
literature. He is theauthor and co-authorof three books on Thermodynamics
and Fluid Flow and Heat Transfer in
gas/liquid-mixtures.
His scientific activities involve

thermodynamics,
heat transfer,optical measuring
techniques, two-phase flow, power engineering andsafety of nuclear power plants. In the field of thermodynamics, valuable contributions
include measurements of thermophysicalpropertiesof water, anumber of fluorocarbon
components and mixtures ofthese refrigerants, and flame propagation phenomena
in combustion.
In heat transfer, Professor
Mayinger’s
research
activities cover a wide range of important problems
in the field of convective transport
processes withand without phase-change,
including the cooling ofelectronic equipment and heat transfer augmentation.
He made outstanding contributionsin the field of twophase flow, especially on critical heat flux phenomena,
onset of nucleate boiling, spray-coolingunder postdryout conditions, the heat transfer under post-dryout
conditions, the heat transfer under critical and supercritical thermodynamic
conditions,pressure drop,
phase distribution,
entrainment
in multiphase flow,
and scaling laws of multiphase flow and heat transfer.
Professor Mayinger is one of the rare scientists whoapplied his contributions
in fundamental
research topractical
problems ; the applicationof his basic
research in thermodynamics,
heat transfer and twophase flow is aimed to power and process engineering.
He is one of the pioneers in the field of optical measuring techniques.
He developed
holographic-interferometry methods like the real-time-method
and thetwo-wavelength-method
for simultaneously recording
the temperatureand the concentration
fields withcombined heat and mass transfer processes. For veryfast changing temperaturefields, such as the one at
the phase interface of condensing
bubbles, he combined the holographic
interferometry
with the highspeed cinematography.
In recent years he concentrated
his work on the computerized,
fully
automatic
evaluationof holograms
and interferograms.
He used the holographic
interferometry
not cmly for studying heat and mass transfer processes
but also in non-destructive
material testing and forinvestigating
sprayformation
behindinjectingnozzles.
In the field of reactor safety, he focuses his researches mainly on problemsof emergency
corecooling, following loss of coolant accidents and on
the interaction
between molten core debris and thewall of the pressure vessel or the concrete shield after
hypotheticalcatastrophic
accidents. He also studied
the two-phase-how
processes in componentsof theprimary loops under such catastrophic
accident scenarios.
Professor Mayinger has also been very active inthe university administration,and in national andinternational
scientific organizations.
He served as theDean of m~hanica~ engineering faculty twice at theTechnical University of Hannoverand once at theTechnical University of Munich. He is a member of
the German Nuclear Safety Commission,
formerly
advising the Federal. Minister for Inner Afdirs andnow the Federal Minister for Environmental
andNuclear Safety Affairs. For three years he served as
the chairman of this Nuclear Commission.
namely1983/84 and 1990.
In the ‘Deutsche Forschungsgemeinschaft’(German Research Association)
he served for 6 years(1977-1983) as member of the senate. for 5 years(1978-1983) as member of the main executive committee and for 3 years (19841986) as member of thecommitteefor ‘Sondcrforschungsbereiche’(Specialresearch areas). He has also served in numerous scientific and technical committees in Bavaria.
Professor Mayinger has also been very active internationally. He is a member of the Scientific Advisory
Board and of the Executive Committee of the International Centre for Heat and Mass Transfer since1985. He has been elected chairman of the Executive

Committee of the International
Centre of Heat andMass Transfer in 1990. He presented keynote lecturesin various international
conferences.
He has been
invited as lecturer in many universities and research
centres around the globe such as in Brazil. China,Japan, Saudi Arabia, Turkey, U.S.A. and in Europe.
He has been invited to NATO ASTs on thclmal sciences
several times as one of the distinguishedlecturers.
He is the editor in chief for the international journal
W&me- und Stoffiibertragung published by Springer.

ProfessorMayinger
is a distinguishedteacher.
Many of his students are now professors or hold leading positions in various companies in Germany andin different countries around the world.
Although he is very active and bus), with teachingresearch and international
co-operations
to keep thisreputable, internationallyknown Chair at a highest
possible level of standard,Professor
Mayingerisa devoted
husbandand loving father. Professor
Mayinger and Mrs Mayinger must feel very proud andblessed since their daughter Brigitte MD, specializes ininternal medicine, son Thomas is an attorney and theyounger son Wolfgang is doing his Ph.D. on materials
science at the Technical University of Stuttgart.
We are sure that Professor Maying&s
